Radiography is one of the methods of research, the basis of it – obtaining a fixed image by means of x-rays. Usually get the result on x-ray film or withdrawn (if used for digital devices) on the screen or paper. The study is based on passing x-rays through the tissues of the body. Typically use x-rays as a diagnostic method. For more accurate results use of x-rays in two projections.
Radiography OGK (chest) – the most common method of survey that allows you to identify pathology of the respiratory and cardiovascular systems, ribs, thoracic spine, occurring in various injuries and diseases.
How are x-rays? Passing through the body and organs they are absorbed in different ways. The result is the x-ray. Tissue more dense structures appear white on it, those are softer – dark. After development and drying, the radiologist evaluates the resulting picture. X-ray picture of the lungs will show all pathology, if any, will indicate disease.
Modern digital cameras simplify the procedure, the radiation dose is significantly reduced. And there is a mobile equipment that allows you to examine bedridden patients.
Chest x-ray helps detect the following pathologies in the body:
Radiography is used for tracking the dynamics of recovery in the treatment of pneumonia. However x-rays cannot be called a universal method of diagnostics. For example, the nature of the tumor x-rays to assess you can't, also this study is limited to stationary patients. For such exceptional cases, computed tomography is used.
When the decoding result x-ray picture OGC doctor evaluates what the size and shape of the mediastinum, the structure of the thorax and soft tissues, transparency of the lung fields, the intensity of the figure, the position and structure of roots of the lungs, form of the pleural sinus and diaphragmatic domes.
For the procedure radiography OGK does not require special training. The doctor recommends to remove clothing and jewelry from the area that is to be irradiated. You also need to remove all items that may interfere with the study (eyeglasses, dentures). If there is a need for the presence of a relative of the patient, it is worn on a protective lead apron.
Removing his clothes, the patient is positioned in front of the photographic plates. The doctor leaves the room to the console, his team needed to lift their shoulders, cuddling up to the plate and hold your breath for a while. To move this is not. If the patient cannot take a vertical position, it is placed on the table. Help him in this case, the relatives or the nurse.
The Examination is painless, does not cause any discomfort. The only discomfort – a cool room temperature. The x-rays will be ready within 15 minutes. It will give you immediately along with a description. Based on this, the doctor will make a diagnosis or refer for further examination.
X-ray examination is widespread in dentistry. The not only provides the ability to track pathology, but also reveals deviations in the structure of the jaw. X-ray diagnosis is important in selecting optimal treatment options.
There are several types of x-ray snapshot in dentistry
X-ray scan of the teeth is performed according to the recommendations of the dentist: in case of detection of caries, abnormal occlusion, diseases of periodontal tissues, with pulpitis, cyst, injuries of the jaw, abscesses.
The study recommended the patient to remove all metal items, jewelry: they can distort the pictures. The procedure depends on the type of the image. Is the study a few minutes. The radiation is minimal dose. The session takes place in a special room. The patient occludes the photosensitive film, it must be between the machine and examined the tooth.
In the study with computer radiovisiograph the patient must put on a special apron, the sensor is installed on the investigated area and is attached to the apparatus. The result is displayed on the computer.
The use of orthopantomograph radiograph is performed in the following way: the patient is to the camera, the chin is fixed on the support. Teeth clamped unit which does not close the jaws. The patient must be stationary. The device rotates several times around the head. Images can be taken on the same day.
On the basis of x-ray picture of teeth, the doctor writes the conclusion, which indicates the number of teeth, size and their location. All detected abnormalities will also appear in the conclusion.
The picture shows the location of each tooth, the tilting condition of the bones. Dimming in the picture indicate the presence of pulpitis, denticle. Defects in tooth enamel indicate tooth decay. Where the density is reduced, the visible illumination. If the tooth is difficult, the tooth structure is deformed, the formation of granulomas.
Can be discovered a cyst – a clear outline of the uniform structure of elongated shape. Cysts located at the tooth root, it can be small and large. Large cysts can affect just two teeth. Chronic periodontitis is seen as a darkening in the picture at the top of the root. When periodontal disease is reduced bone marrow visible region, visible atrophic and sclerotic processes of change.
In some cases, the doctor recommends to do the x-rays of the spine?
The x-rays it is recommended to perform two projections: lateral and frontal. Description x-ray image makes the radiologist, he estimates the contours of the vertebrae, the spaces between them, the intensity of the color, the presence of growths. After that an experienced specialist are able to diagnose, to determine the probable prognosis and the need for surgical treatment.
For a picture of the upper spine does not require special training. If we study the lumbar-sacral region, it is recommended to prepare in advance:
The Examination for the patient is absolutely painless. Held over 10-15 minutes. Pictures with description immediately handed out.
