Computed X-ray densitometry in lung emphysema diagnostics
Abstract
A new method of lung emphysema radiological diagnostics is reported. It is based on computed technologies. The computed X-ray lung densitometry was applied in lung emphysema patients with the aid of softwarehardware equipment "Dia-Vid" for evaluation of lung function local disturbances. The main features of local lung ventilatory disorders in lung emphysema patients were revealed which were rigid zones (RZ), or areas with increased lung transparency which are not changed during breathing in the identified zones. A close correlation was found between results of computed X-ray lung examination and pulmonary function parameters that reflects a bronchial passability and lungs’ filling with air. The opinion is spoken out that the method proposed could be widely used in clinical practice for pulmonary obstructive diseases diagnostics as long as its basic configuration is quite cheap and it significantly decreases radial burden to patients.
