Визуальная оценка диффузных заболеваний печени по данным гамма-топографии

Аннотация

The diagnosis of diseases of the hepatobiliary system has always been a great clinical and scientific interest due to the rapid progress that today undergo radiological techniques , to date, not only observed trend exhaustion diagnostic problems in this sphere , but on the contrary , every day reveals new horizons for research. The study included 135 patients with diffuse liver diseases . Gamma topographic survey was conducted using the " Scinticart -800 " an hour after intravenous administration of the radiopharmaceutical Tc - Tehnefit 50-100 MBq activity . An important factor in the formation of gamma- topographical findings are particularly payment ways circulatory disorders and liver metabolism at different stages of changes porto - liverals circulatory . With progression of disease charactertion RPD distribution varies from uniform in the initial stage to formulate a focal plated and terminal stages . Difference in the contrast image of the liver and spleen is used to assess functional activity liver and , in particular, transition of hepatitis to cirrhosis. Gamma topography allows to visually assess the anatomic and morphologic structures of the liver, both to explore the functional state of the liver parenchyma , as well as to determine the nature, extent and stage of liver inflammation
