Fluorography and x-ray of the lungs

An ordinary person is difficult to understand the intricacies of diagnosis. For example, fluorography and x-rays of the lungs are used today to identify respiratory pathologies. What is the difference between these types of surveys and what to choose? Which procedure is safer and more informative?

A snapshot of the picture is different!

Fluorography and X-ray of the lungs: what is the difference

Polyclinics use pulmonary X-ray and fluorography to diagnose pulmonary pathologies. Differences between them exist, and are quite large. They are:

  • X-rays will give the doctor more information. All characteristics of the pathology (shape, area of ​​injury) are more clearly visible on the X-ray. And fluorography (FLG), if it helps to detect deviations from the norm, it is not suitable for making an accurate diagnosis. Even a layman will notice how much the X-ray differs from the X-ray;
  • X-rays can be done several times. This presents a much lower risk to the patient;
  • PHG gives a significant radioactive dose, and information - an order of magnitude less;
  • a x-ray image displays only the lungs and the heart (that is, only the chest is exposed to radiation). X-ray also covers other areas;
  • X-rays cannot be done without a referral, while fluorographic examination is a mandatory preventive procedure. Everyone can pass it without visiting the doctor;
  • the x-ray result will be given to the patient on the same day after a short period of time. Answer FLG can be picked up on another day.

A natural question arises: if this is the case, then why are we always sent to FLG? Answer it is very simple. Mass free examination of the population with the help of X-rays will cost the state much more expensive - about 2-3 times. If you do x-rays, you can significantly save on consumables. And another factor: not all clinics are equipped with modern x-ray rooms. A fluorography, although outdated, can be offered literally in every medical institution.

Thus, a paradoxical situation arises. If a person underwent fluorography and the answer raised doubts with the doctor, then he gives out a referral for an x-ray. That is, the patient will receive a double dose of radiation.

When can I do x-ray?

FLG is a procedure that once a year all adults without exception must undergo. Thanks to this survey, it was possible to reduce the growth rate of the incidence of tuberculosis. This procedure is used for screening purposes. When it is necessary to arrange a mass check with quick results, it is precisely the pulmonary fluorography that comes to the rescue. What does such an examination show? It will help to identify the following problems with the bronchi and lungs:

  • the presence of foreign bodies;
  • severe inflammation;
  • fibrosis;
  • a tumor (if it has acquired significant dimensions);
  • cavities and infiltrates (seals).

Since the FLG has a low resolution, it is impossible to make an accurate diagnosis based on such a snapshot. But it is still possible to suspect deviations from normal indicators. That is, lung screening in this way does not always help to detect cancer in the initial stages.

At the same time, some doctors insist: if a person has no complaints about the work of the respiratory system, then there is no point in taking an extended picture.

Detail of the image - the main feature that differs x-rays of the lungs. What does a classic radiograph show? It will allow you to see with 100 percent accuracy any objects (which should not be present in the respiratory organ) having a size of up to 5 mm. That is, with a pronounced clinical picture of pneumonia, tuberculosis or suspected cancer, an X-ray will definitely be assigned (moreover, in several projections).

If a person is an active smoker or his professional activity involves causing harm to the respiratory organs, which is fraught with the development of dangerous diseases, then it is advisable for him to regularly take x-rays. The only problem is that in order to conduct this examination in a state clinic, a referral from a doctor is required, and he will not give it without good reason. In paid diagnostic centers for such an analysis will have to pay at least 200-500 rubles.

Something Important About Radiation

X-ray and pulmonary X-ray

It is clear that it is impossible to enlighten the lungs and not receive a portion of radiation. Doctors may give conflicting information about the extent to which fluorography and pulmonary X-rays threaten health. What is the difference between one and the other diagnostics, the numbers will convincingly show. It is considered that the maximum permissible dose, which can be obtained within one year, is 5 m3. If film radiography is done, you will receive 0.1 m3v at a time (this is almost 50 times lower than the safe level). If you go to the FLG, then 0.5 m3v will pass through your body. This also does not reach the dangerous border, but still 5 times more than with X-rays.

Currently, the digital FLG has replaced the film. It allows to reduce the radiation dose to 0.05 m3v. Similar parameters for X-rays are only 0.075 m3v. Therefore, in order to maintain health, you should choose more advanced methods of examination.

Based on the foregoing, we can conclude: if you do not want to receive a large dose of radiation, go for an x-ray. He will give more data on whether everything is in order with your lungs, heart and bronchi. But nothing harmless (when it comes to the use of rays) does not happen. However, in any case it is better to go through one procedure or another than to start a disease. The final decision on the choice of examination technology should remain with the doctor, so you should be treated by a specialist you trust.
