NEW METHOD OF X-RAY DIAGNOSTICS OF DISTURBANCES OF LUNGS VENTILATION FUNCTION BY MULTIDETECTOR COMPUTED TOMOGRAPHY
The aim of the research is to develop a new method of quantitative assessment of lung ventilation function disturbances based on the analysis of 3D modeling of multidetector computed tomography results. The work deals with 3D volumetry, which is the new method of X-ray diagnostics of lung ventilation function disturbances. The methodology of conducting the diagnostics, the possibilities of its practical application to some diseases (chronic obstructive pulmonary disease, bronchial asthma, anomalies of lungs development and tuberculosis) at the example of specific researches are presented in the article. It is shown that the method of 3D volumetry based on the multidetector computed tomography has indisputable advantages not only in comparison with other methods of X-ray diagnostics but also with functional methods of research commonly accepted in diagnostics of lung ventilation function disturbances. This method has a bigger potential than traditional computed tomography and opens new possibilities of 3D modeling of multidetector computed tomography. Thus, for example, volumetry allows to make a quick assessment of the degree of lung ventilation function disturbances not only visually, but also quantitatively; the construction of 3D models gives an unquestionable advantage in comparison with traditional images at standard multidetector computed tomography. Due to 3D volumetry it has become possible to assess the function of each lung separately and if necessary the function of a separate part of the lung affected by the pathological process whether it is air cavity or a limited part of hyperinflation at the defects of lung development. The identification of pathological zones of hyperinflation in lungs can become the means of prediction of development and of clinical course of the pathological process, inflammation, and addition of the infection.
