Blood circulation in the lungs: radiologic methods of diagnosing microcirculation changes in the small circle of circulation

Abstract

Radiological diagnosis of diseases of the respiratory system includes a number of methods based on various ways of obtaining information about the state of the chest organs. Most of the applied methods are aimed at identifying structural changes in the lung parenchyma, however, with the development of lung diseases, the pathological process affects all anatomical structures of the lungs, without exception, including the vascular bed of the lungs, primarily due to its microcirculatory level, therefore, this process requires special attention of specialists to the methods detecting changes in the pulmonary microvasculature. Depending on the purposes of the study, various methods of radiologic diagnosis should be used in combination. The review provides a brief anatomical characteristic of the capillary bed of the lungs. History of the study of blood circulation in a small circle is discussed, and modern methods of radiologic research are used to detect lung diseases.
