Causes of darkening in the lungs on x-ray. Is darkening the picture a death sentence? Focal opacification syndrome

Darkening in the lungs on a fluorography image - what is it? This is a question asked by many patients whose fluorography results are ambiguous.

Darkening can mean anything, so if the radiologist issued such a conclusion, there is no need to panic - most likely, you will be prescribed an additional examination.

Darkening in the picture can be either a sign of an incipient disease or a common defect in the film.

Darkening in the lungs may be a consequence of:

• inflammation;
• bronchitis;
• tuberculosis;
• tumors, including cancer;
• injuries;
• ingress of foreign bodies;
• abscesses;
• accumulation of fluid;
• smoking.

IN medical practice this is the most common reasons the appearance of darkening. Among them there are diseases that are life-threatening to the patient and his environment.

Therefore, if a darkening is detected on fluorography, then this is always a reason to begin a more detailed examination using other diagnostic methods.

Darkening in the lungs, detected on fluorography, indicates disorders both in the lungs themselves and in adjacent areas.

The spot may be an enlarged lymph node, a formation on a rib, vertebrae, or an enlargement of the esophagus.

Shape and location of darkening

A single spot on the image indicates a tumor. Multiple spots indicate inflammation, tuberculosis, fluid accumulation and the presence of tumors in other organs.

If the darkening is at the apex of the lung, then tuberculosis can be suspected. A spot with blurred boundaries indicates pneumonia, especially if the person being examined is weak or has a high fever.

But in some cases, pneumonia occurs without fever. A certain geometric shape of the spot can tell the doctor that the patient has pulmonary infarction, hemorrhage.

Lungs of a smoker on fluorography

People who smoke are at risk for lung diseases. Over the course of a year of smoking, approximately a glass of toxic resins deposits on the tissue of this organ.

Smokers, more than others, need an annual fluorographic examination.

Changes in the lung tissue of a smoker occur quickly, but, as a rule, they are not displayed on fluorography.

Fluorography helps to identify not the fact of smoking, but neoplasms that have arisen as a result of this bad habit.

How smoking affects the lungs is clearly shown by another examination - x-ray.

X-ray shows how different the organs are healthy person and a smoker.

The lungs of a non-smoker in the picture will be of a light, uniform color, since they are filled with air, the pattern can be clearly distinguished blood vessels. The lungs of a smoker are covered with dark spots.

What might darkening look like in a photo?

Dark spots in the lungs can be of different sizes and shapes, located in any place of the lung. The following classification of blackouts is accepted.

Focal darkening of the lungs on fluorography - they look like nodular spots less than a centimeter in diameter on the picture. They appear as a result of tumor processes and vascular disorders.

This type of darkening may well turn out to be serious illness, but a fluorographic image does not give the doctor the opportunity to make an accurate diagnosis.

Focal darkening accompanied by high temperature, general weakness, cough, can talk about focal tuberculosis- specialized studies are prescribed to identify it.

To clarify the diagnosis, the patient is sent for a more informative examination: computed tomography.

You will need to undergo laboratory tests: donate sputum, blood, urine.

Focal darkening also appears with this rare disease, like a pulmonary infarction, in which hemoptysis is possible.

In addition, pulmonary infarction is accompanied by inflammation of the veins of the legs, heart pain, and pain in the side.

Round dark spots of the lungs are round-shaped single spots, the diameter of which is more than a centimeter. These spots on the image can indicate either an inflammatory process or the presence of tumors (both benign and malignant).

It is for this reason that if there are round-shaped shadows in the image, the doctor will definitely prescribe additional procedures.

Segmental darkening of the lungs on fluorography - in this case, the spots on the image have triangular shape, there may be several of them.

Causes of segmental darkening of the lung or lungs - endobronchial tumor, presence of a foreign body, trauma.

If there are several darkened segments, then this is a sign of pneumonia, tuberculosis, central cancer, narrowing of the central bronchus, metastasis.

Shapeless darkening of the lungs on fluorography - they look like spots without clear boundaries and do not have the correct geometric shape.

They most often talk about staphylococcal or common pneumonia. Staphylococcal pneumonia has a primary and secondary form.
Photo:

Primary appears as a result of inflammatory processes in tissues, secondary - when a purulent focus is introduced into the body (this can happen with osteomyelitis, adnexitis).

Staphylococcal pneumonia in Lately occurs more often than usual.

Also, darkening in an indefinite form may indicate exudative pleurisy. In all these cases the patient will have elevated temperature, cough, weakness.

Darkening of the lung lobe on fluorography is when the affected lobe is clearly visible on the image and has clear contours.

Darkening of the lung lobe is a sign of any “chronicle” in the lungs: cirrhosis, purulent lesions, bronchiectasis.

Darkening with liquid on fluorography - indicates pulmonary edema, which occurs during ischemia, poisoning with certain toxins, and vascular diseases.

If, after visiting the fluorography room, they gave you a stamp and sent you home in peace, this means that no pathology was found, since in otherwise The office worker is obliged to notify the patient or his local doctor about the need for an in-depth check.

Interpretation of fluorogram and other methods

After visiting the fluorography room, the patient receives a picture and its transcript.

Comments on a photo may contain the following information:

• enlarged roots - indicates bronchitis, pneumonia;
• stringy roots - pathological changes due to smoking, bronchitis;
• in-depth drawing of blood vessels - indicates poor circulation in the lungs, problems with the heart and cardiovascular system, bronchitis and pneumonia, the initial stage of oncology;
• fibrous tissue - trace of earlier past diseases, operations, injuries;
• focal shadows are actual shadows. If the shadows are accompanied by an increase in the vascular pattern, then this indicates pneumonia;
• calcifications - indicate that there was contact with a tuberculosis patient, but healthy body enclosed the stick in a calcium “shell” and further dissemination no infection occurred;
• changes in the diaphragm - consequences of obesity, pleurisy, diseases of the gastrointestinal tract;
• sine - in healthy lungs pleural folds form air cavities; in patients, these cavities are filled with fluid or are in a stuck together state.

Spots on the image may indicate several dozen diseases, so it is necessary to continue the examination.

For further examination, the doctor sends the patient to a pulmonologist and oncologist, where he will have to undergo specific procedures.

Diaskintest is a method for diagnosing tuberculosis. Unlike the Mantoux test, which very often shows an erroneous result, Diaskintest does not react to BCG and makes it possible to diagnose tuberculosis much more accurately.

Sputum tests - laboratory examination of sputum. Detects tuberculosis bacteria, malignant cells, various impurities characteristic of certain pathological conditions.

Computed tomography of the lungs is optional, but informative method diagnosis of diseases of the lung tissue, pleura and mediastinum.

Diagnostic bronchoscopy of the lungs or tracheobronchoscopy - is performed using flexible endoscopes that are inserted through the nose.

An x-ray is taken before the procedure chest to prevent airway obstruction.

The examination allows you not only to see the lungs, but also to collect material (this is absolutely painless).

The material is subsequently subjected to histological, cytological, and bacterial examination.

Blood test for tumor markers - helper method cancer diagnostics, allows you to identify in the blood specific proteins produced by malignant tumor cells.

Blood is taken from a vein on an empty stomach. The number of tumor markers increases not only in cancer, but also in a number of infectious and inflammatory diseases.

When interpreting fluorography, there are errors, but the method itself cannot be called ineffective. Using fluorography, dangerous diseases such as tuberculosis and lung cancer are diagnosed.

This is a quick and inexpensive method that can be used for medical examination of the population.

Often only thanks to him it is possible to identify new cases of tuberculosis infection and begin to treat the patient in a timely manner.

The results of fluorography can reveal not only the onset of tuberculosis, but also many inflammatory diseases and processes affecting the lungs, bronchi and nearby tissues.

Be examined at for preventive purposes preferably once a year. If there is a history of illness respiratory system or there is a risk to the respiratory system due to professional activity, can appoint additional examinations– it is not dangerous to health.

Types of dark spots in the lungs

What is it - darkening in the lungs on fluorography, and how can they be classified?

Depending on the lesion, darkening of the following nature can be seen in the image:

• focal;
• segmental;
• shared;
• focal;
• indicating the presence of liquid;
• indeterminate form with blurred contours.

All changes in the lung tissue are reflected in the image and change the clinical picture.

The causes of darkening in the lungs can be:

• pulmonary tuberculosis in various stages and forms;
• oncological processes;
• collapse of the lung - the formation of an impassable area for air;
• purulent-inflammatory processes - abscesses;
• problems with the pleura - the membrane that separates the respiratory system from the rest of the organs located in the chest;
• accumulation of fluid in the pleural area.

Dark spots in the image also appear when there are problems in the organs, which also fall into the focus of the X-ray machine. This happens when you increase lymph nodes, caused by inflammatory processes in any part of the body, neoplasms on the spine or ribs in the chest, problems with the esophagus - for example, with its pathological expansion.

If during fluorography a darkening is revealed in the image, this does not mean that they will immediately “lock you up” in a tuberculosis dispensary and begin to “force” feed you tuberculosis pills. As you can already see, a dark area in the image does not always indicate problems with the respiratory system.

First, a detailed X-ray examination will be prescribed, during which the chest will be photographed in several projections. It is very important that the image is then read by an experienced radiologist to avoid errors that could seriously affect the patient's health.

If there is darkening in the lungs, the diagnosis is made based on detailed X-ray data.

Reasons for blackouts

Focal opacities look like nodules in the lungs small size– up to 10 mm in diameter. Cause their appearance vascular disorders, initial stages oncological processes and diseases respiratory organs. To accurately identify the cause, in addition to radiography, it is necessary to do a computed tomography scan and pass general tests, which, in addition to the “on duty” ones - urine and blood, also includes sputum.

Collecting sputum for examination is a common procedure for pulmonary diseases.

Despite the patient's complaints of cough and chest pain, a blood test may not show any changes. Such clinical picture is typical for focal tuberculosis, so routine examinations will continue to accurately establish the diagnosis.

Focal shadows also appear in the image during myocardial infarction or lung cancer. Symptoms of a heart attack may resemble in many ways acute development tuberculosis.

Additional symptoms: chest pain, displaced in left side and radiating to the side and back, hemoptysis. With myocardial infarction, thrombophlebitis of the lower extremities develops.

Lung cancer is detected through blood tests.

Segmental shadows are visible on the image as segments with clear contours - in most cases they have a triangular shape. If the segment is single, this may be a consequence of: traumatic injury lung tissue, the presence of an endobronchial tumor of various etiologies, the presence of a foreign body - children often inhale small parts toys.

If there are several segments, then the patient may be diagnosed with:

• pneumonia varying degrees severity in acute or chronic form;
• tuberculosis;
• narrowing of the central bronchial branch due to stenosis;
• the presence of metastases in surrounding organs;
• accumulation of fluid in the pleural area.

The lobar darkening has clear contours that are clearly visible in the image. This picture indicates the presence of chronic pulmonary diseases– purulent tissue lesions, bronchiectasis or others. If bronchial obstruction is visible on the image, the presence of a malignant process can be suspected.

Focal opacities appear with the following problems in the lungs and surrounding tissues:

• pneumonia;
• accumulation of fluid in the pleural tissue - effusion;
• the occurrence of eosinophilic infiltrate – helminthic infestation;
• bronchial asthma;
• abscess.

Cause focal shadows in the tumor image various etiologies, bone calluses that have grown on the ribs after fractures.

Causing increasing swelling of the organ, accumulates when intravascular pressure increases during ischemia or general intoxication body.

Pathologies expressed by darkening of an indeterminate shape can be signs of many diseases:

• inflammatory processes caused by staphylococcal infection;
• accumulation of pleural fluid;
• heart attack;
• exudative pleurisy.

Therefore, you should not diagnose yourself if, when you receive a form from the fluorography office, there will be an inscription on it indicating the presence of changes. Next, a detailed photograph will be taken and only then, according to the specialist’s description, a decision will be made on further diagnostic activities to determine how to treat the disease that has arisen.

Photo transcript

Conclusions from a radiologist with a suspected diagnosis may look like this:

1. The roots are compacted and expanded - possible: bronchitis, pneumonia, bronchial asthma.
2. The presence of stringy roots in the image is characteristic of exacerbations chronic bronchitis and may indicate smoking abuse.
3. Increased vascular pattern may be a symptom of: problems of cardio-vascular system, inflammation, bronchitis, cancer in the initial stage.
4. Availability fibrous tissue indicates a history of respiratory disease.
5. If the radiologist’s report says: focal shadows, this is a signal for the doctor: to prescribe additional examinations. Such symptoms indicate the presence of pneumonia in the upper or middle sections or tuberculosis.
6. If there are clear spots on the image caused by the presence of calcifications, the patient does not require treatment. The subject came into contact with patients with tuberculosis or bacterial pneumonia, but his body defeated the disease on its own. The infection was isolated by calcium salt deposits.

Pictures can also be described as follows.

There are aperture changes. Such anomalies develop according to genetic reasons, because of adhesive processes in the chest, chronic diseases digestive organs– liver, esophagus, stomach, intestines.

If an x-ray shows a shadow in the lungs, this may indicate dangerous pathology or physiological state. Remember that a radiograph is a summation of the thickness of anatomical structures.

X-ray darkening syndrome in the lungs appears on the image as a white spot of various sizes (focal, segmental, subtotal, total). Many anatomical structures and pathological changes.

If an x-ray shows darkening in the lungs, what does this mean? Let's take a closer look in the article.

What causes “darkening” in the lungs in the picture?

Depending on location White spot May be:

• pulmonary;
• extrapulmonary.

Darkness in the lungs occurs due to:

• tissue compaction inflammatory process;
• tumor growth;
• localized abscesses or cysts;
• collapse of lung tissue with atelectasis;
• tuberculosis.

Extrapulmonary causes of darkening in the image:

• liquid in pleural cavity;
• exudative and encysted inflammation of the pleura;
• pathological formations in the spine and ribs;
• mediastinal tumors;
• aortic aneurysm;
• swollen lymph nodes;
• diseases of the esophagus and intestines (hernias);
• pathology of the diaphragm;
• lipoma in the costophrenic sinus.

The main causes of dark spots in the lung on an x-ray

Describing the causes of spots in the pulmonary parenchyma, it is convenient to classify all formations into: limited and widespread.

Limited dimming radiologists consider a shadow that does not exceed 1.5 cm in diameter. In shape, these formations can be round, oval, lumpy or irregular in structure. With encysted pleurisy, the white spot has a triangular shape. Similar shadows can be seen in atelectasis.

Causes of extensive darkening:

• exudative pleurisy;
• miliary tuberculosis;
• pulmonary edema.

White spots in the image are also caused by artifacts ( foreign bodies).

For correct setting diagnosis when identifying blackout syndrome, the radiologist must have knowledge of nosological forms of diseases and have practical experience interpretation of chest radiographs. Young specialists are afraid to perform radiography in a lateral projection, since in these images the image is formed by summing up many anatomical formations, which significantly complicates the detection of diseases.

Sometimes darkening in the pulmonary parenchyma is a consequence of pneumonia and persists in a person for years. Such patients are classified as X-ray positive, which is indicated accordingly in the X-ray diagnostic passport.

X-ray of the lungs showed a dark spot - what is it?

If there is a dark spot on the x-ray, increased airiness of the lung tissue should be suspected. The syndrome can be limited or widespread. The shape is: round, oval, triangular.

A round dark spot is observed on an image of the lungs when hydatid cyst. True, around the formation there is a clear white outline formed by the wall of the cyst.

Emphysema (increased airiness of the alveoli) is manifested by total clearing on both sides. With a local emphysematous bulla, the dark spot is limited to several ribs or a segment.

X-ray diagnostics of this syndrome is not difficult for radiologists who have seen many images of the chest organs during their practical activities.

How dangerous is darkening or clearing in the lungs?

Darkening and clearing in the pulmonary parenchyma - is it dangerous? To answer this question, the doctor should analyze a set of laboratory and instrumental methods and examine the person. Only after this can he say whether enlightenment or darkening is really dangerous.

X-ray diagnostics – auxiliary diagnostic method. It is designed to supplement information about the condition of patients’ organs and tissues. If you pay attention to the protocol for describing the radiograph, the end point there is the “conclusion” of the radiologist, but not the “diagnosis”. This approach is adopted in medicine due to the fact that x-ray radiation“passes” through many anatomical structures, some of which are not visible on film.

It is easy to differentiate total darkening after obtaining the results of other diagnostic methods. Because of this in sanitary rules it is written that x-ray examination is carried out only after all other types have been carried out diagnostic studies. The approach allows not only to reliably verify the conclusion, but also to select the optimal projections to obtain maximum information from the images.

The danger of tuberculosis

Today medicine is for timely diagnosis and the prevention of pulmonary diseases requires citizens to undergo an annual fluorographic or x-ray examination. Decoding an X-ray of the lungs allows you to strictly monitor the condition of the lungs of the subjects and detect them in time possible pathologies. In particular tuberculosis. Despite the fact that medicine is developing rapidly and very successfully, tuberculosis still leads the list of common pathologies of the respiratory system. Koch's bacillus, capable of infecting any organ, with enviable consistency chooses the lungs. Weakened immunity contributes to the active proliferation of tuberculosis bacteria, which is easily determined by x-ray examination. It will absolutely reveal dark spots on the lungs, which indicate the occurrence of pathological process. The larger the percentage of the surface of the lungs that is infected, the larger the spots. Their presence indicates the severity of the condition, being a sign of destruction of lung tissue.

Clinical picture

Spots on the lungs can be multiple (with disseminated tuberculosis) and single (with infiltrative tuberculosis). This infection is a chronic, sluggish disease, the causative agent of which is the already mentioned Koch bacillus. It is mainly transmitted by airborne droplets, and the presence of an infected person is not at all necessary: ​​it is often enough to use poorly washed cutlery or a towel, or simply stand not far from the place where the patient just passed. For bacteria to multiply, certain conditions are necessary: ​​reduced immunity, weakened body, frequent stress. Also, Koch's wand feels great in an organism affected by chronic disease or are pregnant.

Detection of tuberculosis

Getting an infection into the body does not guarantee the rapid onset of symptoms - a person still for a long time may feel good, not suspecting that a destructive process is in full swing in the body. It often happens that a person learns about the disease only during a routine examination, which includes mandatory fluorography. The picture shows spots on the lungs, and only specialists can decipher it: they know that the light areas of the picture are “darkenings”, and the dark ones are “clearances”. These are the characteristics of negativity.

Treatment of tuberculosis

Spots on the lungs, indicating the presence of tuberculosis, are not a death sentence today. The disease is successfully treated, although the process is long and difficult. Its essence is to destroy the pathogen - the same Koch bacillus that has become a favorite lung tissue, - with help antibacterial drugs. Although medicine is now at the stage active development, there are still no other methods of treating tuberculosis. Only the medication regimen and the medications themselves may differ, depending on the type and stage of the disease. Take care of yourself!

Every Russian citizen knows that annual preventive medical examinations mandatory procedure. One of the most important examinations- , which allows you to detect various diseases on early stages their development. Alarm bells for doctors it is a pathological darkening of these organs.

Darkening in the photo of the lungs.

There are many reasons that lead to the occurrence of such darkening, therefore, to determine them as correctly as possible, experts do not disdain other examinations.

After all, certain darkening is just an indicator that inflammation (of any nature) is occurring in the body. Why does darkening appear in the picture? To answer this question You need to study this topic carefully.

Key Features

In most situations pulmonary diseases accompanied by the appearance of compactions. Such problems occur due to a decrease in diameter or blockage of air passages at specific locations on the surface of the lung, and radiologists see dark spots on the fluorogram.

Symptoms of this kind are confirmation of the occurrence or development of pathologies in the lungs themselves or surrounding cells.

Shadows indicating pulmonary diseases often have different intensities, clarity and dimensions. Such areas are evidence of the following health problems:

• Inflammation and tissue compaction;
• nodular neoplasms (tumors);
• clogged air passages;
• development of tuberculosis processes;
• fluid filling of the lung pleura (the layer of membrane that covers and protects every organ in the sternum);
• inflammation of the pleura;
• pustular abscesses.

Fluorographic images often contain dark spots manifested due to defects of any organ behind the ribs. Such symptoms are confirmation of such problems:

1. Enlarged lymph nodes.
2. Tumors on the vertebrae/ribs.
3. Diseases of the esophagus, etc.

Types and description of dark spots

The type of pathological damage to the tissues of the respiratory system greatly influences the way the shadows are located, their dimensions and geometry. Based on this, everything dark spots Fluorograms may show:

• Focal;
• formless;
• focal;
• liquid;
• segmental;
• share type.

Let us consider in detail each type of such shadows.

Focal shadows

This type of dark spots are small nodular areas up to 10 mm in size. Usually they manifest themselves in the event of any inflammation or problems with blood vessels. Such darkening is often a sign of the onset of the development of any pulmonary diseases.

Based on one fluorogram, it is impossible to determine exactly what the reasons for the appearance of lesions and their nature are, so doctors always prescribe patients to additionally undergo a CT scan or radiography. It is also advisable to conduct laboratory tests, during which the indicators and contents of the mucous membrane, urine, etc. are examined.

In situations where, when focal darkening is detected, the patient has an elevated temperature, general malaise, headache, incessant coughing attacks, severe chest pain, there is high probability diseases of bronchopneumonia.

A focal shadow on an X-ray of the lungs, which indicates internal bleeding.

When the results of a blood test do not confirm the presence of any abnormalities, development is possible.

The main symptoms of this disease are decreased appetite, malaise, causeless dry cough, frequent irritability, strong pain in the sternum. If this diagnosis is suspected, doctors prescribe a series of studies.

Another common disease with focal opacities is pulmonary infarction, which manifests itself as thrombophlebitis in the legs, pathology of the heart muscle, etc. The last problem that can be discussed in the presence of a focal shadow on a fluorographic image is peripheral cancer.

Single cases of focal shadow on a fluorogram have round shape, and their size often exceeds 10-12 mm. Such darkening in the lungs is considered a sign of inflammation, which manifests itself due to the occurrence of such diseases:

• Inflammation of the lung;
• local effusions (water channels in the lungs expand);
• eosinophilic infiltrates - this disease is accompanied by mechanical lesions of the lungs, bronchial asthma;
• abscesses.

Focal shadow in the photo.

One of the most rare causes the appearance of such shadows on fluorograms is the use of highly targeted, potent medications, availability of purchased or congenital cysts, which are filled with liquids/gases.

This type of darkening can also indicate problems with tumors:

• Benign (fibroma, adenoma, lipoma, hamartochondroma);
• malignant (metastasis, sarcoma).

Often round dark spots confirm the presence calluses which are caused by rib fractures. Doctors must take this fact into account when deciphering film fluorograms.

Segmental spots

Dark spots on fluorograms can be distributed as separate segments of any diameter/shape (usually triangular). There can be up to 10 such dark spots on a lung, and doctors make a diagnosis of diseases based on a comprehensive examination. The appearance of single spots on the lung is usually considered a symptom of the following diseases:

• Endobronchial tumor;
• foreign bodies, mechanical damage lung tissues.

In the case of clear viewing of several darkened areas on film fluorograms, we can talk about the following problems:

• Chronic pneumonia or acute form this disease;
• tuberculous inflammation;
• centralized oncology;
• central bronchial constrictions;
• concentration of any fluids in one place of the pleural tissue;
• malignant metastases.

Shapeless spots

Fluorograms often contain darkened spots that are not shaped like other species. Usually their appearance is not similar to certain geometric shapes, and there are no clear boundaries of the shadows. In most cases, such lung pathologies confirm the symptoms of staphylococcal pneumonia. This problem can develop in the following forms:

1. Primary. This disease manifests itself in the presence of inflammation in the lung/bronchus.
2. Secondary. This form develops as a result of hematogenous infection from a purulent focus (due to osteomyelitis, adnexitis or other similar diseases). IN last decade the secondary form of staphylococcal pneumonia has begun to spread much faster, so people must undergo fluorography every year to detect this disease at an early stage.

Dark spots of this kind can often occur due to edema of the pulmonary tissues, pulmonary effusions of blood, tumor-like neoplasms, concentration of fluids inside the pleura in one place and the presence of another disease that can be accurately determined using laboratory research. When similar diseases Patients often experience fever, cough, malaise, and headaches.

Share shadows

In the case of lobar darkening in the lungs, their contours are clearly visible in fluorogram images. Usually they differ in shape by their convexity, concavity, straightness, etc. Lobar darkened spots usually confirm that people have any chronic pulmonary diseases, which are easily determined using computed tomography.

Most often, the lobar spot is a confirmation of the development of cirrhosis, bronchiectasis, and the appearance of purulent cavity. Any of the indicated pathologies on a CT image is very different from cancerous tumor, therefore exactly determine malignant neoplasms is necessary only if a person has bronchial obstruction due to inflammatory or scar formations.

Darkened areas filled with liquids

The image shows fluid in the lungs.

This type of darkening in the lungs on fluorograms usually indicates developing edema. Such problems may arise due to high blood pressure inside the pulmonary vessels or due to a decrease in the content of protein substances in the blood. The presence of fluid in the lungs is an obstacle to the proper functioning of this organ.

Pulmonary edema occurs:

• Hydrostatic. These problems arise due to high pressure in the blood vessels, so the fluid leaves the bloodstream and penetrates the alveolar areas (the extreme points of the respiratory system), gradually filling the lung. Similar pathology most often occurs due to ischemia or other chronic problems heart muscle.
• Membranous. The cause of these edemas is the strong impact of toxic substances that damage the lining of the alveoli and then exit the blood vessels of the lung.

The correctness of diagnosis is greatly influenced by qualification level, practical skills and theoretical knowledge radiologists studying and describing fluorograms.

The equipment used to perform the X-ray examination also plays a very important role. It is for this reason that it is advisable to contact reliable clinics where real professionals and experts in their field work, who recognize each type of darkening in the lungs.
