Due to the possibility of solving a large number of technical problems, the method of computed tomography (CT) venography is widely used nowadays. However, it has not yet received clinical recognition in the diagnosis of chronic venous diseases. This article analyzes the results of studying the CT venography use, describing the methods of indirect and direct contrast CT venography. It also shows the possibilities of using contrast CT venography in the diagnosis of deep vein thrombosis and discusses the opportunities concerning the combined use of CT venography and CT angiopulmonography in the diagnosis of pulmonary embolism. Contrast-enhanced CT venography can become an indispensable tool in studying the patterns of the topographic and anatomical structure of the venous bed. Using the example of their research, the authors demonstrate the possibilities of direct CT venography of the lower extremities. The  need for more accurate topical diagnostics with 3D imaging of the lower extremity and pelvic venous system with CT venography is due to the growing interest of vascular and interventional surgeons in testing and more active administration of endovascular correction of venous blood flow in phlebological practice. The use of magnetic resonance imaging (MRI) and CT imaging will help to clarify the data of clinical anatomy, as well as to look differently at some of the main path-dependent hemodynamic links in the development of cardiovascular diseases in patients with venous diseases.

Keywords: computed tomography, computed tomography venography, magnetic resonance imaging, magnetic resonance venography, chronic venous diseases.
