The study of the possibilities of perfusion computed tomography (PCT) in determining the nature of focal lung formations in the absence of morphological verification, doubtfulness of the data of native CT — the actual problem of thoracic radiology. The aim of the study was to Refine the methodology and capabilities of PCT in determining the nature of formations of the lungs. Material and methods of research: The data of PCT of 29 patients with benign and malignant changes in the lungs on 128 slice computed tomography with data processing at the workstation were analyzed. Conclusion: Low-dose scanning Protocol for lung PCT allows to obtain reliable data on the angiogenesis of focal lung formations. Upon receipt of the perfusion map, the ROI is placed on the area of the highest blood flow. With sufficient PCT data on the nature and prevalence of lung disease from CT with contrast enhancement may refuse. Average PS, TTP are the main and leading factors in determining the nature of the lesion in the lungs. Qualitative and quantitative analysis of PCT data allows to speak reliably about the nature of foci in the lungs.
