Clinical significance of Tc-99m colloid liver angiography for the diagnosis of hepatocellular carcinoma

Journal Article:

Abstract

Tc-99m phytate liver angiography was accomplished in 191 cases with focal liver disease at the same time of performing conventional liver scintigraphy from July 1978 to Feb. 1981. This simple method was considered to be useful to appreciate tumor vascularity in the liver, which was shown as dynamic radioactivity in the defect of the liver scintigram. Hypervascular pattern was defined as a high-radioactivity on the arterial phase of RI angiography, which corresponded to the filling defect on the static liver scintigram. This pattern was influenced by three factors, i.e. pathological vascularization of the tumor, size of the filling defect and position of the defect in the liver. In 29 cases (74%) of 39 hepatocellular carcinoma, hypervascular pattern was observed. When mean diameter of defect was more than 5.5 cm on liver scintigram, it was supposed that hypervascular pattern should be observed in probability of 84%. The smallest mean diameter of defect in which this pattern was seen was 3.0 cm. When a filling defect was situated at the posterior region of the right lobe of the liver, it was sometimes difficult to appreciate the vascular pattern.
