Every patient who needs to undergo a medical examination should know how an x-ray differs from one. These methods are based on the same principle, but different equipment is used for each method.

Distinctive features

Every person must undergo a routine examination using fluorography once a year. It is used to examine the organs of the chest tissue, mammary gland and bones. X-rays are used to clarify the diagnosis. These methods differ in cost. Due to its low price, fluorography is used for mass examinations of patients.

Using an x-ray, the doctor obtains an image of the part of the body being examined on photographic film. This technique is best used to confirm/refute a specific disease and dynamically monitor the development of the pathological process.

The main element of an X-ray machine is the one in which the radiation is created. The rays pass through the organ under study, affecting the film. Fluorography is considered more harmful than x-rays, since the latter technique is characterized by a low dose of radiation. Due to the high radiation dosage, the 1st method is used no more than once a year.

During fluorography, a shadow image is photographed from an X-ray or optical converter screen onto a small-format film. Its dimensions range from 110x110 mm. The screen is characterized by high sensitivity, unlike film for radiography.

To obtain an image in a small format, an X-ray fluorography apparatus is used. It is presented in the form of a fluorograph, a booth with protection and a radiation source. The technique under consideration is used to diagnose cancer, tuberculosis and other ailments of the bronchi and lungs. The difference between radiography and x-rays is that the image is reduced 14 times. To conduct the first examination, film and digital images are used.

Bad influence

And fluorography has a negative effect on the human body. For X-ray, the dose control level is 1.5 m3v/g. With film fluorography, this figure ranges from 0.5-0.8 m3v/g, and for digital fluorography - 0.04 m3v/g.

To undergo a chest examination, the level of EED is taken into account.

If the examination is carried out using an X-ray machine, then the image appears on the appropriate film. During fluorography, the image first appears on the screen and is then photographed on a camera. This technique allows you to diagnose the disease. In X-rays, rays pass through the body and onto film. Another technique is characterized by additional conversion of rays into visible light. The reduced image is then focused onto photographic film. Based on the results, an additional detailed examination is prescribed. Therefore, fluorography or x-rays are prescribed in each case individually.

Radiography of the chest organs is used by doctors for screening and lungs. For this purpose, mobile and stationary equipment is used. In modern medicine, film technology is being replaced by digital technology, which greatly simplifies working with images. The image is displayed on the monitor screen, printed, transmitted over the network and saved in the database. This type of examination is characterized by low radiation exposure and low costs for film and other additional materials.

Experts distinguish 2 methods of digital fluorography. The first method is to photograph the image on the screen. For this, a CCD matrix is used. Another technique is based on layer-by-layer transverse scanning of the chest. Fan-shaped beams of radiation pass through a linear detector. This method is characterized by a low dose. It will take longer to obtain an image using this technique than with CCD radio photography.

Fluorography, like radiography, is a study based on obtaining images of internal organs when X-rays pass through the patient’s body. However, these methods are not the same. Despite the general principle of obtaining diagnostic information, their goals, execution techniques and information content are different.

Fluorography and radiography of the lungs

Lung X-ray and fluorography are prescribed to different categories of patients. Each of these studies occupies its own niche in the diagnosis of respiratory pathology. Let's try to figure out what these methods are, what their advantages and disadvantages are, and how they differ from each other.

Indications for the study

A chest x-ray is ordered if illness or injury is suspected. Fluorography is a screening procedure. Its task is to identify lung pathology in the early stages. This method is the first link in the chain of diagnostic studies. It is indicated for all patients, regardless of whether they have specific complaints.

A chest x-ray allows you to diagnose the following pathological conditions:

Respiratory diseases: pneumonia, tumor, abscess, emphysema, pulmonary edema.
Conditions resulting from chest trauma: fractures of the ribs, sternum or clavicle, hemothorax, pneumothorax.
Pathology of the pleura: exudative pleurisy.
Diseases of the heart and large vessels: enlarged heart due to certain defects, aortic aneurysm.

However, for the conditions described in the last two paragraphs, x-rays are not the leading diagnostic method. When examining the heart and blood vessels and identifying fluid in the pleural cavity, preference is given to ultrasound. This method is more sensitive than x-rays and does not expose the patient to radiation.

Examples of fluorograms

Fluorography is designed to detect early signs of lung cancer and tuberculosis. However, it is not always possible to make an accurate diagnosis using a fluorogram due to its low information content compared to x-rays. To clarify the cause of pathological changes in the lungs, it is necessary to resort to other diagnostic methods - CT, MRI, ultrasound, radiography.

How many times can a photo of the lungs be taken?

The frequency of preventive examinations is regulated by regulatory documents on x-ray diagnostics. So, according to SanPiN 2.6.1.1192-03, fluorography should be done once a year. The study is indicated for everyone except pregnant women and children under 14 years of age. These recommendations are mandatory. Exceptions, unlike X-rays of the lungs, are not made under any circumstances.

X-rays are performed if chest disease or injury is suspected. The number of photographs per year is not limited by standards. There is no maximum permissible dose. In each case, the question of the need to do an X-ray of the lungs is decided individually, taking into account indications and contraindications, and the consequences of refusing the diagnostic procedure. In other words, chest x-rays are performed as many times as necessary.

Fluorography is not the same as x-ray. Its goal is a preventive examination of the population. Radiography is performed to clarify the diagnosis if data from other studies and patient complaints indicate the presence of a specific pathology.

When the study is contraindicated

X-ray of the lungs is well tolerated, does not take much time, and does not require special preparation. The same can be said about fluorography. However, the latter has a larger list of contraindications than radiography:

Pregnancy. X-ray radiation is very dangerous for the embryo. The shorter the period, the greater the likelihood of developing malformations or miscarriage. For this reason, even a suspected pregnancy is an absolute contraindication for fluorography.

During pregnancy, fluorography is contraindicated

With x-rays, not everything is so clear. In fact, in this case, the patient is exposed to radiation. However, if refusing the test or postponing it to a later date will lead to serious complications, the doctor will recommend an x-ray, regardless of the consequences for the fetus. Thus, pregnancy cannot be considered an absolute contraindication for chest radiography. In addition, an examination of the chest organs, if precautions are taken (shielding of the abdominal area), is not accompanied by such a serious risk to the embryo as, for example, an image of the pelvic bones.

Childhood. Fluorography is not performed on patients under 14 years of age. X-rays are acceptable at any age. Of course, pictures of the lungs are not taken on young patients unless necessary. As in the case of pregnant women, the risk from not performing a diagnostic procedure must exceed the harm from radiation exposure.

Thus, fluorography of the lungs has strict contraindications, from which no exceptions are made. The same cannot be said about a chest x-ray. In certain circumstances, an image is prescribed even in early pregnancy. In fact, radiography has no absolute contraindications.

Radiation dose

Fluorography and x-ray of the lungs are two options for x-ray examination of the chest organs. What is the difference? Both methods involve radiation exposure to the patient. In this case, radiation exposure depends not only on the type of method (fluorography or x-ray), but also on the characteristics of the diagnostic equipment.

Digital radiography system

The image obtained on the film apparatus is transferred to a medium - x-ray film. Digital X-ray makes it possible to store diagnostic information in electronic form. Such an archive does not take up much space. Data is not lost in it, it is easier and faster to find it than among films. If necessary, the image can be printed, and any number of copies can be made without resorting to repeated photographs.

But the advantage of digital cameras over film cameras is not only faster results, no costs for additional materials (in particular, film), ease of archival storage and data retrieval. The main advantage of such equipment is low radiation exposure. Thus, with fluorography using a film apparatus, the patient receives 0.5 mSv per image, while with a digital one, only 0.05 mSv. For chest radiography, these figures are 0.3 and 0.03 mSv, respectively.

From the above data it is clear that one chest x-ray is accompanied by less radiation exposure than a fluorographic one. And this statement is true, regardless of which diagnostic device - film or digital - was used. However, not all so simple.

During fluorography, one photo is taken. X-rays of the lungs are usually performed in 2 standard projections: frontal and lateral. Sometimes there is a need for additional photographs: in oblique projections, lying on your side. In this case, the total dose will exceed that received during fluorography. Thus, when radiography is performed in 2 standard projections, the patient is exposed to radiation of 0.6 and 0.06 mSv (the study is performed on film and digital devices, respectively).

Radiographs of the lungs in two projections

The difference in radiation exposure between radiography and fluorography seems significant when comparing indicators for one image. However, to diagnose pathology of the chest organs, it is often necessary to conduct research in several projections, which increases the radiation dose. Preventive examination is always limited to only one image.

Information content of the method

How does fluorography differ from radiography? In the first case, the picture turns out smaller. The size of the fluorogram with the small-frame technique is 24x24 or 35x35 mm, with the large-frame technique - 70x70 or 100x100 mm. The image of a chest x-ray is larger, which allows for a detailed examination of the organs and pathological changes in them.

The small frame size for fluorography is a way to save on film. However, this significantly reduces the information content of the method. That is why diagnosing the disease only on the basis of a fluorogram is difficult. The latter allows you to see not all the changes visible in the overview image. Thus, the pulmonary pattern is difficult to assess by studying only fluorography data.

On the issue of interchangeability of methods

Which is better: chest x-ray or fluorography? X-ray is a simple and informative method for diagnosing pathological conditions of the respiratory system. Fluorography is a study aimed at early detection of lung diseases. Both methods are variants of x-ray diagnostics; they are based on the same principle of image acquisition. However, the goals pursued are different, so it is not entirely correct to talk about choosing between these studies.

Low radiation dose.
Simplicity (no need for special training, few contraindications).
Allows you to identify among a large number of patients who are suspicious of a particular pathology and refer them for further examination.

What is the difference between X-ray and fluorography? The study allows not only to suspect, but in most cases, to reliably establish the cause of changes in the image. X-rays are not used as a screening method. It has the same contraindications as fluorography. However, if necessary, the doctor can neglect them.

Mobile fluorograph

Why not take one x-ray of the lungs in a direct projection instead of annual fluorography? The radiation dose is lower and the information content is higher, which reduces the likelihood of additional clarifying studies when identifying pathology. In addition, when examining with a digital device, the consumption of film can be greater than with fluorography.

However, radiography is not a high throughput technique. And this factor is extremely important for screening. Preventive examination should not only be safe and informative, but also allow examination of as many patients as possible in a short period of time. In this indicator, fluorography is superior to x-rays and, together with its other advantages, becomes the optimal method for the early detection of respiratory diseases.

All adults undergo a fluorographic examination every year. X-ray is a similar test, but it is not a mandatory diagnosis. Why does this happen and how do these x-ray diagnostic methods differ? To answer this question, it is necessary to consider x-rays and fluorography separately. This will help identify the similarities and differences between them.

What is X-ray

Radiography (or x-ray) is an x-ray method for studying the internal structures of the human body. The image is obtained by exposing organs and tissues to x-rays. Moreover, the image (photograph) of the organs is life-size. Radiography happens:

Survey (for example, chest x-ray);
Targeted (a specific organ or area of the body is studied).

There are currently 2 types of X-ray machines in use:

Film (old model). The radiation that a person receives during the examination is 0.27 m3v;
Digital (modern model of the device). With its help, the radiation exposure to the patient is significantly reduced (up to 0.03 m3v).

The result of this examination is a clear image in which microscopic pathological changes (about 2 millimeters in diameter) are recorded. However, X-rays are used only to clarify and make the correct diagnosis. It is not prescribed for preventive purposes.

What is fluorography

Fluorography is a radiological diagnostic method based on the use of X-rays. Using this method, the chest organs (lungs, heart, large bronchi and aorta) are examined.

The result of the study is a photograph. However, its size differs from the image obtained by radiography. In this case, the photo is small (11 cm x 11 cm). Its distinctive feature is that it can be in digital format.

Devices for fluorography are also divided into 2 types:

Film. When conducting an examination with this device, a person receives radiation equal to 0.55 m3v;
Digital – modern equipment, the radiation of which is significantly lower than older models and is equal to 0.05 m3v.

Fluorography is used for preventive purposes. It helps to identify respiratory diseases at an early stage of development. However, it should be noted that this examination is not carried out on children under 14 years of age and pregnant women under any circumstances.

What is the difference between X-ray and fluorography?

Both x-rays and fluorography belong to x-ray research methods and at first glance are no different. However, there are enough differences between them. To understand how X-rays differ from fluorography, it is necessary to consider their characteristics in comparison.

What is the difference between fluorography and chest x-ray?

Chest X-ray and fluorography are aimed at examining organs such as the heart, right and left lungs, bronchi and aorta.

Let's look at the difference between fluorography and x-ray of the lungs. It should be noted that fluorography and chest x-ray have different purposes. If fluorography is more often used during a preventive examination, then x-rays are prescribed only if lung or heart disease is suspected. This is due to the information content, that is, the quality of the images. X-rays produce clearer images. They are larger in size, which allows for a better view of the structure of organs and pathologically altered areas.

If we talk about which study is more revealing, then radiography wins.

If we compare them by radiation dose, then at first glance fluorography loses. Because the dose of X-rays is higher. But one should take into account the fact that when diagnosing pathologies of the heart (congenital defects) and lungs (pneumonia, pneumothorax, hemothorax, and so on), radiography in 2 or more projections is required. Therefore, the total radiation dose is the same, or higher for x-rays.

No preparation is required for fluorography and simple x-rays. If radiography is performed using a contrast agent, preparation will be required. The attending physician will warn you about this.

What is better to do: chest x-ray or fluorography? Based on the above arguments, it is impossible to answer this question unambiguously. After all, these diagnostic methods are each good in their field of application. However, if you suspect diseases of organs located in the chest, preference should be given to radiography.

Indications for fluorography

All adults and adolescents 15 years of age and older must undergo fluorography once a year. However, not all people follow this, which can lead to negative consequences. In this regard, it is necessary to identify groups of people who should under no circumstances avoid this preventive procedure:

People working in the field of education (teachers, educators);
Workers in “harmful industries” (chemicals, dyes, asbestos, cement, silicates, steel production, coal mining, and so on);
Medical staff of maternity, perinatal, infectious diseases departments, anti-tuberculosis hospitals;
Patients with chronic diseases.

Indications for X-ray of the lungs

An X-ray of the lungs is prescribed if the patient has certain complaints and symptoms that indicate the presence or development of pathology. Quite often, this symptom is a prolonged cough that cannot be treated. However, there are others Indications for X-ray of the lungs:

Possible harm from fluorography or x-rays

When prescribing an x-ray examination, the doctor must evaluate the benefit to the person and the harm that may be caused to the person. Many people exaggerate the harm that this examination can cause. However, one should not deny the fact that x-rays and fluorography are harmful.

The body is harmed by the radiation that a person receives during the procedure. What is the effect of X-rays on organs and tissues:

A short-term change in blood composition, which can lead to anemia;
The structure of proteins (proteins) changes;
The process of origin, development and vital activity of cells is disrupted;
Early aging of cells and tissues;
Degeneration of cells and tissues.

Adverse effects of X-rays can lead to the development of malignant tumors.

Radiation exposure is especially dangerous for pregnant women and children. Pregnant women exposed to radiation may experience spontaneous abortion and disruption of labor. But what suffers most is the fetus, which is at high risk of developing congenital diseases and developmental abnormalities. In children, X-rays can cause growth and development problems. And also in a small child there is a high probability of developing a cancerous tumor in the area exposed to dangerous rays.

Now you know how X-rays differ from fluorography and which procedure should be chosen in different cases. Also on our website you can find answers to popular questions about x-rays and fluorography -.

Every person has to deal with procedures such as fluorography and x-rays of the lungs. Most often, fluorography is a mandatory procedure during routine examinations to identify respiratory diseases, and x-rays have to be done for those in whom the doctor detects severe lung diseases or to identify injuries in the thoracic region.

But for many, the question remains unclear - how fluorography differs from x-ray of the lungs and what is better, fluorography or x-ray. This article will tell you about the specifics of these procedures and what their advantages and disadvantages are.

What is fluorography

Fluorography is one of the methods of X-ray diagnostics, which consists in the principle of photographing shadows in the area of the chest organs. Not so long ago specialists used the method capturing the lungs from a fluorescent screen and then transferring them to photographic film, but today the images are transferred to a digital image.

Medical workers began to actively use this procedure in 1930, thanks to the Soviet scientist S.A. Reinberg, who promoted the prevention of pulmonary diseases using fluorography. Thus, doctors were able to diagnose tuberculosis and pneumonia with a small radiation dose, in contrast to fluoroscopy, already known at that time. During one x-ray diagnostic session, the average radiation dose was 2–2.5 mEv.

The method of mandatory preventive fluorography has long been legalized by the government, since such screening makes it possible to combat the massive spread of tuberculosis in the country. When examining the lungs by fluorography You can identify darkened areas as large as five millimeters. It is worth noting that in such a study, the dose per dose of radiation is no more than 0.015 millisievert (mEv), but the permissible radiation dose for preventive studies is 1 mEv. Thus, fluorography is safe for the human body.

Despite the safety of fluorography, many during professional medical examinations, not wanting to waste time in long lines at the fluoroscopy room, may subject themselves to the procedure of lung radiography. But you should remember, that such time saving has a negative impact on the human body and contradicts the principles of patient safety, since the radiation dose from x-rays increases up to 100 times, unlike fluorography.

The fluorography procedure should not be performed:

pregnant women;

What is a lung x-ray

X-ray of the lungs is a method for diagnosing any pathological changes in the human respiratory organs by recording these changes on film.

In its own way, examination of the thoracic region using X-ray diagnostics is a better alternative to the fluoroscopy procedure. This is due to the fact that with X-rays of the lungs it is possible distinguish affected areas sizes from two millimeters. As noted earlier, if fluorography is a method of prevention, then fluoroscopy is a direct procedure that allows you to clarify a possible diagnosis or refute it. A chest x-ray is prescribed if the doctor suspects tuberculosis, cancer, pneumonia, bronchitis, etc.

During the procedure, a short-term but high radiation load is created on the thoracic region and the information obtained appears on x-rays. When prescribing this procedure, the doctor must take into account the number of x-ray examinations performed per year and only if if the radiation dose is not dangerous Such a diagnosis is prescribed for the patient’s life. Otherwise, a mutation may occur at the genetic level of cells, which poses a great danger to human life. It is worth noting that when radiography is performed using more modern equipment, it can reduce the dose of radiation exposure to the body.

The radiography procedure, as in the case of fluorography, should also not be carried out:

pregnant women;
people planning to conceive a child.

Fluorography or X-ray of the lungs - which type of examination is better to choose?

When deciding on the choice of lung diagnostics, you need to take into account the peculiarities of the procedure and the practical benefits of both fluorography and x-rays. If you have any doubts about choosing the right procedure should be consulted with specialists who, from the point of view of medical indicators, will be able to prescribe the necessary procedure necessary for a person in a particular situation, be it preventive measures or the identification of pathogenic processes in the lungs, taking into account the physiological characteristics and with the least risk to health.

But both doctors and patients should remember the principle of working with radiation diagnostic equipment - the benefit from obtaining information should be higher than the causative harm to a person from the radiation he receives.

Is it possible to refuse fluorography or x-ray diagnostics?

Some patients wonder whether it is possible to avoid X-ray diagnostics or fluorography. From the point of view of official legislation, every person has the right to this, but at the same time he independently takes responsibility for your own health, supporting this fact with a written statement. But there are other legal grounds under which TB specialists may not allow a person to work without this procedure. For example, if you suspect a certain number of diseases that can harm both the person himself and those around him, diseases such as tuberculosis or pneumonia are obvious examples.

In this case, the TB specialist has the right to refer the patient for diagnosis or compulsory treatment. Eg, open form of tuberculosis is dangerous for others, and people exposed to such a disease should be treated in TB inpatient departments of medical institutions.

In the case of pneumonia, in addition to a chest x-ray, there are no alternative methods for reliably confirming the diagnosis and identifying the extent of this disease. In case the patient with this disease refuses to undergo x-rays, then he must understand that such actions may threaten his life. The presence of indirect signs can serve as a starting point for treatment with various medications, including antibiotics, but with a full examination of the lungs using X-rays, it is possible to monitor the course of the disease, the size of the lesions and the pathological severity of the process.

Among the mass media, they are shouting at the top of their voices about the plague of the 21st century, namely tuberculosis.

Tuberculosis is a specific infectious disease that is transmitted by airborne droplets. The causative agent is a pathogenic microorganism of the genus Micobacterium, family Actinomycetacae. The peculiarity of this bacterium is that it can remain in the inactive L-form for a very long time. After the body’s immunity is significantly weakened under the influence of any factors, such as taking antibiotics or a long illness, the microorganism becomes active and causes disease. Why has tuberculosis become so common now? Under the influence of antibiotics, M. Tuberculosis has become more resistant, and the disease becomes more complicated and more difficult to cure. People with a fairly good financial situation began to get sick. If previously it was believed that unprotected sections of society (prisoners, people without a fixed place of residence) were more susceptible to the disease, now this problem has affected everyone. The localization of the process is any, but most often the lungs are affected, followed by bones, then internal organs (kidneys, liver). At this stage, it is important to diagnose pathologists in a timely manner. The question arises: fluorography or x-ray, which is better?

What should you worry about with tuberculosis?

Typical symptoms of tuberculosis:

Cough that lasts more than 3 weeks.
Low-grade fever (37 – 37.5 0 C).
General weakness, malaise;
A specific symptom that around doctors sounds like a “wet shirt” symptom. Its essence is that it is at night that a person sweats a lot, and the next morning he wakes up wet.

Comparative characteristics

What is the difference between fluorography and x-ray of the lungs? Fluorography is a method of x-ray examination, the essence of which is to photograph an image from a fluorescent x-ray screen. Designed for subsequent digitization of images onto film of a certain format, usually 110x110 mm, 100x100 mm, or less desirable, 70 x 70 mm. That is, as a result, the image is always smaller.

An important step in the development of radiology as a science was the widespread use of a new method of fluorography - digital. At the same time, X-ray is also an instrumental research method, but the significant difference is that in it the image is displayed on film, and the resolution of this method is higher. Already, based on the definition, we understand how x-rays differ from fluorography.
It is worth analyzing the advantages and disadvantages of each method in order to understand, X-ray and fluorography, what the difference is.

Advantages of fluorography:

A cheap method that allows for mass examinations.
Speed of execution (3 times less time is spent on execution than on an x-ray).
High throughput.
Ease of storing archives.

Flaws:

In terms of information content, fluorography is inferior to radiography, however, when using large-frame fluorograms, the difference between these techniques becomes less significant.
Less specificity and sensitivity of the method.
The radiation exposure is higher (fluorography - 0.8, GC radiography - 0.26), so it should absolutely not be used by children under 15 years of age and pregnant women.

If we go from the opposite, x-rays are more expensive than fluorography. The main cost is due to the film. But it is precisely this that makes it possible to see a clear and high-quality image of the pulmonary pattern. In terms of information content, it is many times higher, and the main advantage of this screening method is low radiation exposure. And for every phthisiatrician this is a tremendous opportunity to observe processes in dynamics, taking pictures approximately 2 - 3 times every 6 months, which is an unaffordable luxury with fluorography. The advantage of this method is that it can be used in examining children. Specific tuberculin diagnostics in the form of the Mantoux test is carried out up to 14 years inclusive, after which fluorography is recommended. But after 5 years, the Mantoux test is not so indicative, and then the choice is fluorography or x-ray. In addition, no phthisiatrician will see a specific disease on fluorography. This method is a trigger for further diagnosis. Using radiography, you can see a complete picture of the inflammatory process in the lungs, which is very helpful in differentiating diseases of the respiratory system.

The following diseases can be seen on an x-ray:

tuberculosis;
bronchiectasis;
pneumonia (pneumonia);
fractures, cracks, fractures of the bone tissue of the chest cavity (ribs, spine);
congenital and acquired heart defects;
congenital pathologies of the lungs and bronchial tree.

Fluorography and x-ray of the lungs, what the difference is, it became clear. But this is only necessary to understand the essence of the process of examining the body. According to the law, every working person, and especially those whose work involves people (teachers, salespeople, doctors), is required to undergo a preventive fluorographic examination once a year. Students in higher educational institutions, colleges, vocational schools, schoolchildren who have reached the age of 15 are also subject to such examination. Only the doctor can decide whether to undergo fluorography or x-ray of the lungs. After a positive fluorography result, the local TB doctor will prescribe an X-ray examination. Patients should not decide this themselves.
