[Efficiency of Quantitative Analysis of Lung Computed Tomography Findings in Patients with Chronic Obstructive Pulmonary Disease].
To evaluate the efficiency of detection of emphysema in the analysis of lung computed tomography (CT) images using the “Autoplan” program and to compare the data of quantitative analysis and clinical indicators. Material and methods. Sixty patients with chronic obstructive pulmonary disease (COPD) were examined; the diagnosis was confirmed by external respiratory function evaluation; all the patients underwent inspiratory-expiratory CT using a 32-row multidetector CT scanner, followed by postprocessing in the “Autoplan” system. The features of the system were a floating threshold value, constructing a histogram, and the possibility of preserving a report and polygonal models. Echocardiography was performed to evaluate the right heart and to estimate pulmonary arterial pressure. ⋯ Thus, analysis of the lung density CT characteristics provides a physician with objective numerical values, which affect the progression of obstructive changes in patients and the development of signs of chronic cor pulmonale.
