How often can X-rays can do. How often does the child can do x-ray of the chest, lungs, tummy or heads - is it dangerous to the procedure? How do the X-ray of the spine: preparation, which shows the decoding of the result

How often can I do MRI, because medical equipment today is a whole universal complex, capable of identifying a variety of diseases in humans. A huge number of devices and devices are actively used in medical clinics. One of the best techniques for diagnosing diseases can be considered tomograph. This is a high-precision apparatus capable of getting a layer of the organ layer in different planes.

Magnetic resonance tomography helps the doctor promptly deliver the exact diagnosis based on the seen picture. With it, you can reveal tumors, neoplasms, development pathologies and structure anomalies. The principle of the operation of tomograph consists in exposure to particles of the human body by electromagnetic and radio waves, vibrating under radiation.

MRI allows you to examine the body regardless of age and gender. Tomograph details the body structures:

  • soft fabrics;
  • nervous system;
  • musculoskeletal system;
  • the cardiovascular system;
  • brain;
  • urinary system.

MRI can be done required amount Once, but only for the appointment of a doctor, the procedure is absolutely harmless

The time of the MRI diagnostics from 20 to 60 minutes, depending on which organ is scanned, and what survey the purpose is. Diagnostics can show:

  • neoplasms, benign or malignant;
  • anomalies of different nature;
  • metastasis;
  • foci of various diseases;
  • inflammatory processes;
  • pathology of the development of internal organs or tissues.

How many times can I do MRI?

For a long time, research and observations were carried out on how magnetic radiation on the human body affects. Different models Tomographs have passed certain testing, after which the specialists came to the conclusion that MRI is completely safe.

The frequency of the survey depends on the need and testimony. From how purpose the doctor assigns you a diagnosis, the number of scans will depend on. If the patient goes to the magnetic resonance imaging to identify the disease or clarify the diagnosis, it is likely that it is not necessary to pass MRI.

For those who are preparing for surgery, the examination is prescribed to refine the state of the organ and its defeat or interaction with neighboring tissues. Most likely, the procedure will be assigned to the patient and re-after a while, in order to monitor and understand whether the operation helped or how the organ after the transplant is taken.

How often can I do the diagnosis of MRI for a particular patient, determines the attending physician. Due to the fact that the procedure is not available, then without the appointment of the doctor, make a magnetorezonance tomography will be considered.

The main aspect is still a psychological attitude. Often, winding ourselves, the patient worsens blood pressure, will be sick, the heartbeat becomes frequent - it interferes with finding in tomograph, because it is necessary to lie still for a long time.

How many times a year can I do MRI with contrast?

In addition to the classic examination, some patients need to be done. In this case, the procedure will differ only by the fact that the patient is introduced intravenously. This contributes to obtaining clearer shots according to the result of the diagnosis.

Detaped clinical picture Often, everything is necessary before examining vessels, or before neurosurgical intervention, because this will allow the diagnosticity to note even the smallest tumors and education at the stage of birth. The contrast agent is made on the basis of the salts of the Gadolinium and will be contraindicated only to those who have allergic reactions to the composition of the drug.

If there are no allergies, then this kind of MRI will be absolutely safe, it can be carried out as many times as it is necessary during the treatment period, without sharing the categories of citizens by age.

How often can you make a scan of a children's body?

The MRI procedure is prescribed not only adults, but also for children. The reactions to computer diagnostics should not be, because the method is non-invasive. It has already been proven that electromagnetic waves do not have a negative impact on the children's body, because of this restrictions on the number of surveys at some time, there is no time.

However, there are complexities of another nature. For diagnosis on tomograph, a child must withstand quite a long time without movement. This is a difficult aspect, because by nature, its children are very active. The doctor can offer 2 surveys: under anesthesia and using sedatives. Any option affects the baby's nervous system, in view of this, it is not necessary to often scan the body to a child. If there is an acute need for tomography, it is not possible to avoid, however, if there is no testimony, then it is better to refrain from MRI to 3 years, since the use of sedatives cannot be avoided, and this is a colossal load on the child's body.

Is it possible to make tomography of the same organ several times?

The most commonly appointed surveys on tomograph are:

  • a detailed study of the brain;
  • MRI abdominal cavity;
  • tomography of organs located in a small pelvis;
  • scanning the musculoskeletal system.

As a rule, the session is carried out once if a certain organ examination is required. However, if a person did, considering the liver and her vascular systemAnd the scan did not reveal the reason for the deterioration of well-being, the MRI of the same zone will be appointed again, and there is nothing dangerous.

A repeated scanning of the same organ is a safe procedure and is practiced as needed.

How often can I do MRI of the spine pregnant women?

Being in the process of having a child, female organism It is overloading that it often affects the musculoskeletal. Women complain about pain:

  • in the back, lower back;
  • tingling the spine;
  • numbness of the limbs;
  • feeding feet or fingers on the legs.

If there is no visible reasons, then the doctor has the right to appoint MRI of the spine. This procedure will be safe, painless, and it can also be carried out as often as a survey of any other patient.

It is advised to refrain from magnetic resonance tomography only in the first 3 months of pregnancy, when the bookmark of the most important components for the development of the fetus occurs. It is difficult to understand which influence of electromagnetic waves can have formed fruit. But if there is a threat to life future mom, I need to go through MRI.

Is the procedure advocated during critical days in women?

Many experts agree that during menstruation women to do MRI undesirable. This question causes discussion and is harmoniously. It is believed that electromagnetic waves and a magnetic field can affect the work of the pituitary gland, and this will entail a hormonal failure, which may affect not only well-being, but also on the periodicity of the menstrual cycle.

All the same direct evidence of this opinion is not yet, as there are no sufficient studies in such situations. Only a woman has the right to decide whether scanning during special days, or wait for their ending. In any case, the doctor will not be prescribed to the MRI of the MRI, the doctor will not, in order to avoid incorrect data, as stormy hormonal changes occur in the menstrual period in the body.

Is it permissible to repeat brain scanning?

If the patient experiences difficulties in mental activity, the state is constantly worsening, or a concussion was postponed, a head-headed, then the diagnosis of the brain cannot be avoided. The testimony will be such complaints:

  • nausea, dizziness, vomiting;
  • unfortunate loss of consciousness;
  • card and brain injuries;
  • difficulties of function of brain vessels;
  • suspicion of oncological education;
  • stroke;
  • hydrocephalus;
  • torphanation;
  • pain after surgical intervention.

Conduct brain scanning can an unlimited number of times, as required by treatment. But most often doctors do not prescribe MRI as a control procedure more often than once a year. During this period, all processes disturbed by the operation or illness should be recovered, the nervous system will come to normal rhythm, and the consequences of the operation will be on the face. But there are patients undergoing a survey from 2 to 4 times a year. These are those who have dispersed sclerosis. They need it to control the disease. A couple of times a year can be prescribed tomography by those who have a non-metering brain tumor, to observe its condition and influence on the vascular system and artery.

MRI is one of the most accurate and informative methods of modern hardware diagnostics. With it, it is possible to identify pathology and malignant education in the early stages of their development. However, many people have a question: how often can be done magnetorezonance tomography (MRI) so as not to harm your health. Let us dwell on this issue in more detail.

Magnetic resonance tomography is carried out with the help of modern medical equipment: high-precision tomograph of various power. Its action is based on the combination of permanent magnetic field High tension and electromagnetic radiation. Using the apparatus, it is possible to build a three-dimensional model of the object under study and further research.

Tomograph makes it possible to get a series of consecutive shots of fabrics and internal organs. Most often, studies are conducted using magnetic resonance tomography:

  • Musculoskeletal system.
  • Vascular brain system.
  • Soft fabrics.
  • Of cardio-vascular system.

With the help of MRI you can reveal:

  • Malignant and benign education.
  • Pathological processes occurring in the internal organs and tissues of the human body.
  • Single or multiple metastases.
  • Anomalies of various etiology.
  • Location location of foci of various diseases.

On average, the diagnostic procedure using nuclear magnetic resonance takes 30 minutes. Depending on the purpose of the examination and the object under study, it can occupy up to 60 minutes.

How often can you do

The question of how often you can do an MRI of which effects it has on the body, many patients are set, because in diagnostic studies a powerful magnetic field is used. Since it is harmless, MRI does not have a negative impact on the body. Therefore, it is possible to make the procedure as often as justified for diagnostic purposes. However, for the passage of research, the direction of a qualified physician should be obtained. Some modern clinics spend a survey and without direction. But you should not independently decide on the diagnosis. Consult before this with an experienced specialist.

Often MRI are prescribed as a measure of prevention or control. As a rule, it is carried out after surgery to see the effect of the operation.

How often can I do MRI with contrast

One way to get a detailed clinical picture is to use a contrast agent made on the basis of gadolinium salts. Contrast allows you to identify pathological changes at the early stage of their development and malignant formations of even the smallest size (less than 1 mm). As a rule, MRI with contrast is prescribed to explore the head vessels.

Preparations based on Gadolinium salts are non-toxic and fully safe for health. However, some patients may experience individual intolerance to some components included in their composition. In this case, only ordinary MRI can often be carried out without amplification.

How often can the diagnosis of children

MRI can be carried out if necessary not only an adult, but also a child. This method of diagnostic research does not have a negative impact on their health and well-being. Today it is one of the safest, painless and modern. Unlike CT, MRI does not irradiate the body and does not cause almost no side Effects.

However, it is important for doctors to ensure the child's immobility at the time of the survey, otherwise the result of the diagnosis may be inaccurate and non-informative. Therefore, the procedure is carried out under a short-term general anesthesia. Since anesthetic drug has an impact on nervous system baby, it is often impossible to apply it to avoid possible negative consequences.

Of particular importance is the preliminary psychological preparation of small patients before the diagnostic procedure. She is held by parents, explaining to her child, for which the examination is necessary and how it will pass.

As follows from the foregoing, often to do MRI children are not recommended: especially small patients under the age of three. Excess magnetic load will not benefit developing and growing organism.

How often can be diagnosed with pregnant women

Often women who are in the first trimester of pregnancy are not recommended to undergo MRI. Although the negative effect of the high-voltage magnetic field on the human body was not detected, but its impact on the development of the fetus is not fully studied.

It is especially dangerous tomography with the use of a contrast agent. The contrasting drug is able to overcome the placental barrier and have an unpredictable effect on developing fruit.

Despite all of the foregoing, the doctor, nevertheless, can appoint a diagnosis of a woman regardless of its pregnancy. This happens in the event of a patient's life threat when there is a vital tomography. The frequency of research depends on the specific situation.

Is it possible to diagnose repeatedly after a short period of time

So, let's look at how often you can do an MRI, is it possible to do a procedure again after a short period of time. Often, doctors prescribe repeated diagnosis. As a rule, it is necessary to determine how effectively the course of treatment is. On the computer screen, the doctor will be able to see all changes in the underlying organs or tissues in the past therapeutic period.

Since the usual MRI is a fairly safe method of diagnostic research, it can be done several times in a row. In some cases, tomography can be held 2 times the same day. Most often, MRI is prescribed immediately after other methods of diagnostic studies that have not been given for some reason a complete clinical picture.

How often can you do the diagnosis of the brain

The question of how often you can do MRI brain, is a serious and exciting of many patients. This diagnostic method is prescribed at:

  • Nausea, headaches and frequent dizziness.
  • Suspicion of oncology.
  • Obstruction of brain vessels.
  • The presence of brain injuries.
  • Stroke.
  • Hydrocephalius.

MRI is also prescribed after surgery on the brain. This is required to control the patient's condition after the operation and the need to pick up the most effective treatment. Then another question arises, how many times a year you can do MRI brain. You can undergo diagnostics unlimited times. As a rule, the doctor appoints the procedure no more than once a year. However, in the presence of some diseases and suspicion of malignant formations, diagnosis can be carried out as much as possible. For example, with multiple sclerosis, the procedure is carried out at least twice a year. This is necessary to control the development of this disease.

How often can the diagnosis of the spine

Magnetic resonance tomography of the spine is the most popular method of diagnostic research to date. He is prescribed by doctors to identify all changes or violations that occurred in the spine departments. With this method of diagnostics, you can explore departments:

  • Brachial.
  • Lumbar-sacral.
  • Cervical.
  • Temporal mandibular.
  • Hip.

MRI spine can assign with:

  • Suspicion of intervertebral hernia.
  • Obtaining a serious injury.
  • Suspicion of malignant education.
  • The presence of dystrophic disorders in the spine departments.
  • Chronic osteochondrosis.

Answering the question of how often MRI of the spine can be done, we argue that this method of diagnostics can be carried out as often as the attending physician requires. If a specialist prescribes a diagnosis often, you should not refuse it. Thus, it is possible to aggravate the state of our own health. Before conducting research, a doctor of possible risks and consequences should be asked.

MRI of the spine can be carried out even to children. With you on the diagnostic procedure you need to take:

  • An outpatient card of the child.
  • Direction from the doctor.
  • The results of previously diagnostic studies.

Magnetic resonance tomography is modern method diagnostics of a large number of diseases. It is completely safe and painless. Therefore, MRI can be appointed several times a year in the direction of the doctor. Most often prescribed tomography of the head and spinal cord.

Scientists - evolutionists argue that radiation contributed to the emergence of life on Earth. Radioactive radiation is necessary for life in the same way as sunlight And warm. A small increase in the radiation background improves the metabolism in the body, and its decrease (zero radiation) slows down the growth and development of living organisms.

Natural radiation is completely harmless to humans, since the electromagnetic field of the Earth reliably protects all living beings from the most harmful rays. But the appearance of artificial radiation has an increased radiation burden on a human radiation background.

Probably, for this reason, the age of "tamed atom", when its energy is used in all spheres of human social activity, many people suffer from radiophobia. The emergence of this disorder contributed to the accident at nuclear power plants in the 20th century, because the increased radiation background causes irreversible changes in the living organism. In addition, modern medicine is simply unthinkable without tool methods Diagnostics from which X-ray is one of the most sought-after and reliable. How to be a modern person who is literally surrounded by radiation, such as natural and artificial origin? Of course, he has concerns about how to protect himself from her harmful effects. In this context, the question is very relevant, how often can X-ray and how safe is such a study?

Myth about the dangers of external radiation

It should be noted that the source of natural radiation can be air, water, plants, soil and even food (for example, bananas contain potassium natural isotope - 40). The reason for this is the solar radiation and the decay energy of some natural substances. Natural radiation radiation is everywhere and literally permeates all the space around us. Even the person himself is a source of such radiation, since it also consists of substances that can radiate. In the human body there are elements such as potassium - 40 and rubidium - 87, which form a personal radiation background. The source of radiation can be at home in which we live, industrial buildings, construction Materials, Clothing and household items. Another source of radiation, but already artificial origin, are modern electronic devices and devices.

The modern development of science and technology created the world full of radiation. But after reading these lines, you should not be afraid. Very often, people are afraid of what they do not understand or do not know. Yes, in our world, in addition to natural radiation, a lot of artificial radiation has been added over the past hundred years:

  • space satellites covering literally every meter of our Earth;
  • appliances;
  • mobile phones (fears associated with them were not finally passed);
  • radiation from "Wi -fi" networks;
  • personal computers that are in every home;
  • other networks that use the waves of a variety of ranges.

However, all listed radiation types exist on our planet for many years. To this day, no one, even the most avid conspirator, could not prove harm from this type of radiation. In addition, every year all household appliances and electronic devices Improved and become more and more secure. For example, computer monitors are currently emitting much less waves than some more eight years ago. But the radiographic radiation is a completely different matter. It is a closed source of radiation, but which still permeates the body as a patient and a -renantgenologist.

X-ray - what is it?

Let's find out what x-ray is. Radiographic radiation is x-rays, which are short electromagnetic waves. According to radiation, they are somewhat medium between ultraviolet radiation and gamma radiation. They are so powerful that even dense substances such as metal can be shifted, not to mention human tele. This fact allows you to enlighten the body and see the state of bone structures and internal organs on radiographic images. Potentially, this type of radiation can be dangerous to health.

Since this type of radiation has an ionizing property, it is able to destabilize the work of the cells and cause them damage. As a result, damage to the DNA structure may arise, which will affect the health of future generations. Nevertheless, the X-rays are used as a medical and diagnostic agent. When radiation passes through the cells of the body, it ionizes its atoms and molecules, that is, they provoke their division. Therefore, in medicine I use x - low energy rays, and the process of irradiation itself covers a small time interval. For this reason, even often repeated radiographic research is almost safe and harmless.

In addition, different tissues and organs have an individual ability to absorb x - rays. The side effects and the consequences of such studies are dependent on this, as well as the possibility of re-procedure. For example, thyroid, sex and mammary glands have an increased absorption capacity, and such organs as kidneys, bladder, light and liver almost do not suffer from radiation.


How often can X-ray

Nowadays, many people suffer from radiophobia. They are panicly afraid once again to irradiate and, in principle, their concerns are not sufficient. Let's find out how often a radiographic study can be held to avoid negative consequences. According to medical standards, the permissible radiation rate of X-rays - once a year. However, as we wrote above, medical practice suggests that theoretically make X-ray you can at least ten times a year, without negative consequences and side effects. X-ray devices of the past differ from the present as the sky and the earth. They are absolutely safe and do not have a negative impact on the body.

The study can be carried out as many times as necessary for setting the correct diagnosis. The risk of excessive irradiation may appear only if the patient has already received a dose of 60 msv (millizer) for one year.

In addition, the frequency of the procedure varies for different groups of patients. For example:

  • practically healthy people can undergo a study in preventive purposes once a year;
  • persons included in the risk group (smokers, or people working in harmful production) should be studied twice a year;
  • employees of children's institutions (children's gardens and schools), working as teachers, educators, kitchen workers, pass x-ray twice a year;
  • patients suffering from chronic pathologies of the pulmonary system can undergo a radiographic study several times a year, or even several times a month, since it is a forced measure. In this case, the risk of irradiation with X-rays is commensurately less than complications and consequences as a result of incorrect diagnosis or improper treatment.

The procedure may depend on several factors, but is appointed exclusively by the doctor. The doctor also takes into account the date of the last study and the general dose of irradiation, which he received the patient over the past year. What swings themselves - radiologists themselves, then they take security measures that reliably protect their body from permanent exposure. In addition, they come out before retirement and have a longer vacation than other specialists.


Thus, when examining an adult relatively healthy man The following norms are followed:

  • x-ray examination is held once a year (this is not to relate to persons who work in children's institutions and are not included in the risk of the development of pulmonary diseases);
  • most people undergo fluorography, which has a smaller radiation load;
  • x-ray of the teeth are carried out up to 5 times a year, with point exposure to the teeth;
  • investigate the sinus of the brain is permitted no more than once a year, as they are close to the brain;
  • the study of the spine is not desirable to spend more than once a year.

With good health, X-rays are valid for one year. Also, if necessary, such a study, doctors take into account the age of the patient, its current state of health, the presence of chronic ailments and individual characteristics of the body.

How many times can the kid can do

In children, unfortunately, injuries that require x-ray diagnosis occur quite often. But since children have fragile and susceptible organisms, they should be protected from radiation.

Very often occurs in the injury of newborns when they pass through the generic paths. They happen dislocations, sublies, fractures of noses, jaws and skeletal deformation. In this case, for the X-ray, the newborn is put in a special chamber, which prevents the penetration of rays (only except those sites that need research). In this way, children are fully protected from radiation without risk to their health, and the procedure can be carried out even first a week after birth.

Older children 3-4 years old are protected from exposure using special aprons, which immediately in front of the procedure wear a child. Each examination is prescribed by the attending pediatrician and is carried out only with its permission.

There are many diseases when radiography is simply vital for diagnosis:

  • pulmonary diseases, children often suffer from inflammation of the lungs and bronchitis;
  • dental pathology;
  • displays of hip joints;
  • foreign objects in the digestive system, children are very often taken in the mouth and swallow small objects, they are in ears and nose, so in this case without X-ray can not do.

How to conduct the procedure for children? In the same way as an adult, however, the only problem is to fix the child in the right position. Children in their nature are very restless and curious, so they can not be at rest. In some cases, use a special device that reliably fixes the child in the desired position.

Thus, responding to a key question, how often you can irradiate a child, we can say that such research is advisable to spend several times a year (4-5 times as necessary). Rauchery radiation is harmful both to kids and adolescents, if it exceeds the permissible norm. It is possible to exceed the norm only in some cases with the permission of the doctor. It should be noted that at present all modern devices have a weak radiation background, which actually does not have a negative impact on children's organisms.

Permissible irradiation standards

The annual total dose of radiation from natural sources of radiation for a person is 2-5 mSv. However, this does not mean that it is impossible to exceed this norm. In some cases, it is better to diagnose and save a person from complications than to adhere to the established norm. After all, sometimes harm from radiation is much minor than the consequences of serious diseases.

Radiation is able to accumulate in the human body, so the accumulation of ionizing radiation for the entire human life should not exceed 100 - 700 mSv. The permissible irradiation rate varies, since residents of high-altitude regions are subjected to more intensive radiation. However, they are genetically predisposed to an increased radiation background, without any negative health effects.

Radiation doses that receive a person during irradiation of different organs can be compared with natural radiation sources:

  1. With a radiographic study of the chest, a person receives a dose of irradiation of about 0.1 msv. In natural conditions, he receives the same dose within ten days.
  2. When digital fluorography passes, the radiation dose is 0.03-0.06 mSv. In the natural environment, this dose can be obtained for three or five days.
  3. Fluorography on the film exposes human radiation at 0.1-0.2 msv. Under household conditions, this dose can be obtained for fifteen days.
  4. In the study of the mammary glands (mammography), the body receives a dose of 0.7 mSv, in vivo, a similar dose can be obtained within three months.
  5. When conducting computed tomography of the abdominal cavity and computed tomography of the whole organism, the radiation dose is 10 mW. In natural conditions, it is obtained for three years.
  6. In the study of the stomach and the small intestine, the body receives 8 msv, in natural conditions such a dose can be obtained for three years.
  7. In the study of the thick bowel, the irradiated dose is 6 mW, under natural conditions it is obtained for two years.
  8. The resulting dose with a spinal X-ray is 1.5 mSv, in vivo it can be obtained within six months.
  9. In the study of the nasal sinuses, the dose is 0.5-1 msv. In vivo, a person receives this dose for four months.
  10. With a radiographic image of the teeth, the resulting dose is 0.3 mSv, in vivo, a person receives this dose for two to three days.
  11. When determining the density of bones, the body receives 0.001 mSv, in ordinary life this dose can be obtained over several hours.

It can also be noted that when flying by plane, the human body receives a dose of 10 μSv (microsivers), which is similar to several days of irradiation in natural conditions.

Can X-ray do during pregnancy

Each qualified specialist may say that during pregnancy any source of irradiation should be avoided, since it is about the health and life of a child in the womb. But, unfortunately, even in this responsible period, young mothers can get sick and need a radiographic study. How to be in this situation? Of course, to save the mother's life and improve its health is very important, because the normal development of future children, whom it can safely conceive and endure, as if it did not sound. In this situation, the mother's health is paramount and will save it. However, with light diseases and minor damage from radiography, you can refuse. Even the doctor himself will not send a pregnant woman to such a study. It is possible to replace X-ray magnetic resonant tomography, which does not have a significant radiation burden on the body and has no negative consequences.

Each person more than once in his life did X-ray pictures, so necessary to determine the diagnosis. This procedure It is appointed to all age groups: both the babies of the first year of life and the people of old age. Based on this, many people have a question how often can be made x-ray. This article will answer this question in the most detail.

Is dangerous x-ray

The body of all people is characterized by individual resistance to exposure. But despite this, there are generally accepted indicators that are adhered to medical workers. Answering a question how many times a year can be made, some doctors have the opinion that the frequency of this procedure depends on how much the patient's condition requires.

Sometimes frequent control is necessary for timely detection of pathologies. This opinion is not always rational, as a larger number of breast diseases can be identified when using the most safe waysTo which include:

  • general blood analysis;
  • Ultrasound diagnostics;
  • listening.

This judgment is rational in the presence of suspected oncology of lung or pneumonia. X-ray rays load the human body. Especially dangerous x-ray, subject to living in conditions of increased pollution ambientWhat is acceptable to any large industrial city. Of course, if possible, it is better to avoid frequent surveys, but it happens that there is an acute need for radiography.

Important! If the patient suffers from a serious disease, for example, a complex stage of pneumonia, then the procedure is allowed several times a month. In this case, the risk from the disease will be higher possible harm from X-ray irradiation.

Modern diagnostic apparatus is considered a fairly expensive device.

In addition, answering the question of how badly the x-ray, most doctors, argues that serious radiation irradiation is possible only when using the old apparatus. To date, there is a big difference between the X-ray equipment of the last century. The modern apparatus significantly reduces the dosage of radiation that has a negative impact on the patient.

In addition, there is a non-destructive feed of an X-ray, in which the study is carried out on the selected area. Rady load, which is sent to a separate area, patients undergoing CT, MRI.

How often can radiography

It is often the question as far as it is allowed to make an x-ray an adult and a child. This is especially true when the presence of snapshots are necessary to several doctors, for example, for a pulmonologist and a cardiologist. If the condition of the patient is stable, then the snapshot is valid for 1 year.

An unequivocal answer to the question how many times can x-ray, no, since it depends on the individuality of the patient, its condition, age, the stage of the disease, the characteristics of the X-ray apparatus. For various categories there is an individually permitted frequency of the study.

Radiography of the limbs to children is allowed to spend a year no more than 5 times. Rauchery irradiation is harmful not only to kids, but also adolescents. Survey of the brain, the torso is not recommended without the presence of viscous testimony.

Although the modern devices have a weak radiation background, which practically does not have a detrimental effect on the body of children.

An adult survey is carried out based on the following norms:

  • X-ray of light adults can not be done more often than 1 time in the year. However, some professions require a more frequent examination, in this case, the x-ray is replaced with fluorography, which has a more weakened radial impact.
  • Radiography of teeth is carried out more than once a year when the rays are served on the spine or brain. If the shooting is carried out on the side and has a point pointing to the teeth, it is allowed to make a survey to 5 times a year.
  • Nose sinuses are allowed to shoot no more than once a year, as they are close to the brain.
  • The spinal survey is the most unfavorable procedure, with the frequency of which it is better not to overdo. It usually does not exceed once a year.


Stock Foto X-ray teeth - low-volume procedure

Important! CT carries the highest radial load, the number of micro-center for this procedure reaches 1100 mP per hour.

Is it possible to do a nursing woman

There are situations where a nursing woman needs to make X-ray. At the same time, many arises a natural question whether it is possible to feed after the child's procedure. And today the fluorography is held in the walls of the maternity hospital. In this case, it is recommended to feed in front of the procedure. After X-ray, the milk need to write and pour.

Next feeding can be carried out as usual. If a woman is examined for its intended purpose, especially with the use of coloring substance, it is recommended to refrain from breastfeeding. Important! When conducting radiography, a nursing woman, the chest area needs to cover the protective screen.

Is it possible to reduce the negative effects of X-ray with frequent

So that radiography brings as little as possible negative influencesIt is recommended to adhere to the following simple recommendations:

  • first of all, it is possible to strengthen the body by taking antioxidants, for example, the omega-3 complex;
  • it is possible to increase immunity using vitamin preparations consisting of vitamins of group P, B, A, E, C;
  • it should be used before the procedure and after it more fermented milk products;
  • if you eat oatmeal, prunes, grainy bread, then you can remove harmful elements that penetrate the body during the examination.

Radiography is sometimes necessary and far from a useful procedure that allows you to reveal many diseases in a timely manner. Its frequent use can cause irreparable consequences for the body.

Radiography is one of the most important inventions of humanity. Despite the low cost, the procedure high informativeness and shown in a variety of clinical situations.

The principle of operation of the X-ray apparatus reminds principle of receiving a photo. The rays that the special tube applies are displayed on the film, as on the photo card.

Not all parts of the body absorb the same amount of X-ray radiation, so look in pictures in different ways. For example, calcium, in some quantity contained in all tissues of the body, absorbs the most a large number of Radiation, and it is for this reason that the skeleton bone is so bright and clearly visible in the pictures.

In soft tissues, fat layers and calcium muscles is much smaller, which means that they look in gray pictures. The organs containing air look almost black, as most of the rays fall on the film.

Permissible dose of irradiation

International standards have been developed that determine what a safe dose of irradiation can receive an adult during the passage of lung radiography. It is measured by millisyver (msv).

According to generally accepted data, the maximum safe one-time dose with an x-ray study of the lungs and organs of the chest - 7 msvBut when conducting standard studies, a much smaller dose is used.

Important! X-ray irradiation can cause human body significant harm, so its application is always strictly dosed.

Harm caused by radiation depends on the mass of the patient's body and its age. Children and elderly over 65 years old must be exposed to an x-ray-study of the chest only in cases of extreme necessity. For people with overweight, the maximum safe dose of irradiation is higher than for a person with an average body mass index.

Attention! Exceeding permissible doses is fraught with serious consequences: the risk of oncological diseases (special genital organs and blood formation systems) increases, fertility is worse, in extreme cases develops radiation sickness.

How often can the X-ray of the lungs adult man, how many times a year

World and Russian protocols for the prevention of tuberculosis and other pulmonary diseases among adults are recommended by the passage of the hentgen-study of the chest 1 time per year. In some cases, the number of procedures can be increased. These include:

  • inflammatory diseases of the lungs and bronchi;
  • active tuberculosis and tuberculosis in history;
  • treatment of tumor diseases of light and mediastinum.

In these cases, the increased frequency of radiography is due to the extreme necessity, but obtained over the year, the total dose of irradiation should not exceed the established limits.

Reference. The use of modern digital equipment significantly reduces radiation dose compared to film. For example, digital fluorography will give a dose of irradiation 5 times less film, accordingly, it is permissible more often.

Alternatives method

Unfortunately, it does not exist as effective methods Light research as radiography.

Only in some cases it is capable of replacing physical Auscultation and Magnetic Resonance Tomography.
