Computed tomography in the diagnosis of bronchial obstruction in carnivores
The work presents the results of studies of animals with signs of bronchial obstruction syndrome, performed using X-ray diagnosti-cand computed tomography. The main goal of our work is to compare two methods for the diagnosis of bronchial-obstructive syndrome. To achieve this goal, the method of computed tomography was used. The method is based on more high-speed computer systems with new software strategies and can process not only individual sections, but also constantly changing sections of the imaged object, which slowly passes through the X-ray circle. For computed tomography, the animal is placed on the table of the tomograph. At the beginning of the movement of the table relative to the fixed tube and the detector we get the topogram. It looks like a radiograph (which in essence is). According to the topogram, we carried out a tomographic scan (we chose the zone of interest, selected the slope of the gantry). Run the scan. Immediately after scanning, we worked with the image. For comparison, the method of radiography was used. Survey radiographs were made in front and side projections. Radiographs were produced in the optimal packing of the investigated area of the body for tangential ray imaging. Used cassettes without reinforcing screens. The filter and screening grid is not used. When conducting this study, it was found that in most cases the diagnostic capabilities of radiography are rather limited. With the help of computed tomography, narrowing of the bronchi of the bronchi in animals with broncho-obstructive syndrome is most often detected(asthma), as well as structural changes in the lung tissue. The role of computed tomography in the study of patients with bronchial asthma of varying severity is shown. The relationship between changes in wall thickness of various parts of the trachebronchial tree and the severity of bronchial asthma was established, patterns of changes in the geometry of the terminal respiratory tract in patients with broncho -obstructive syndrome were found, and a characteristic pattern of pathological changes in the lung tissue in combination with bronchial asthma with various diseases was found.
