Abstract

The relationship between angiographic findings and those of $^{67}Ga$ scan was evaluated in 30 patients with primary hepatocellular carcinoma diagnosed by either pathological examination or laboratory, radiologic findings. Twenty-three cases revealed hot activities on $^{67}Ga$ scan and definite tumor stains on angiography. Main findings of $^{67}Ga$ scans of 7 cases were isoactivity in 5 and cold area in 2, 5 of which revealed faint or no tumor stain on angiography. Cold areas within the primary hepatocellular carcinoma were noted in 9 cases by $^{67}Ga$ scan. In 6 cases these were due to tumor necrosis. Remaining 3 cases had arterioportal shunt, portal vein thrombosis and one had necrosis as well. These results indicate that gallium uptake of primary hepatocellular carcinoma seems to be relatively correlated with tumor stains on angiography. It is well known that the necrotic portion of primary hepatocellular carcinoma does not uptake gallium and it's the main cause of cold areas on $^{67}Ga$ scan. And we suspect that the hemodynamic changes of primary hepatocellular carcinoma such as large arterioportal shunt, portal vein thromosis may cause the decreased activity on $^{67}Ga$ scan.
