The study is based on the collection of literary material on the abilities of MSCT in the diagnosis of focal liver pathologies. Method - analysis and synthesis of data from scientific electronic libraries of the National Center for Biotechnology Information and elibrary. It was found that computed tomography of the liver is a radiation method based on its ability to move through the biological tissue of the organ under study, which consists in sending rays to detectors, processing hundreds of images obtained, and displaying data on a computer monitor. There are 3 types of computed tomography: standard, spiral and multislice. MSCT is highly sensitive in diagnosing liver pathologies and building very accurate images. The inclusion of MSCT in medicine improved the diagnostic measures of hepatic diseases, including focal formations, since it allowed differential diagnosis, clarification of diagnosis verification, and the establishment of a treatment plan. MSCT diagnoses liver diseases, including focal ones, by visualizing hyperdense and hypodense formations, the presence of calcium deposits, tissue vascularization, density and contours of the parenchyma, the presence of formations, and the activity of the tumor process. MSCT of hemangioma is reflected by cavernous or capillary forms, of uniform density with clear contours. MSCT adenomas are detected in a slight hypodensity of the parenchyma, a homogeneous structure and with even contours. MSCT of focal nodular hyperplasia is characterized by the presence of a hypodense zone with a smooth contour. Hepatocellular carcinoma is defined on MSCT by an uneven and indistinct contour and low density of the parenchyma. Liver metastases are often visualized as round multiple foci of unequal contours and heterogeneous density, as well as the presence of a necrotic process.
