[Comprehensive radionuclide method of studying focal liver lesions].

A comprehensive radionuclide method was used: evaluation of the time course of the absorption of a colloid radiopharmaceutical, a polyposition static examination of the liver, positive scintigraphy using tumorotropic agents and indirect radionuclide angiography of the liver. It has been established that blood flow quantitative indices changed by 1.5-2 times and the prevalence of the arterial component of the hepatic blood flow in all the segments can indicate cirrhotic lesions. A sharp decrease or a complete absence of the blood supply of "cold foci" are mostly observed in abscesses or parasitic involvement of the liver. The prevalence of the arterial component of the blood supply and the lessening of the blood supply value by 40-50% in foci of the lowered accumulation of a colloid radiopharmaceutical only with the preserved blood flow in the adjacent tissues are characteristic of primary tumor or metastatic involvement of the liver.
