THE ROLE OF RADIATION DIAGNOSTIC TECHNIQUES IN THE DIAGNOSIS OF CHRONIC THROMBOEMBOLIC PULMONARY HYPERTENSION

Abstract

The article is an overview of a diagnostic algorithm and capabilities of different imaging techniques in the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH). The authors touch upon imaging approaches specific for CTEPH and idiopathic pulmonary hypertension. The results of comparative studies of diagnostic accuracy of multislice computed tomography, ventilation/perfusion scintigraphy, angiography, and comparative characteristics of the methods, are described. A new method, dual-energy computed tomography, used in the diagnosis of CTEPH and for determining indications for surgical treatment, is highlighted.
