[Liver gamma imaging and its clinical evaluation--an analysis of 80 cases]

This paper describes the preliminary experiences in the diagnosis of 80 space occupying lesions of the liver by liver gamma imaging. Of these 80 cases, there were 38 primary hepatocellular carcinomas, 12 metastatic cancers, 4 liver abscesses, 5 hepatic polycystic diseases, 4 other types of hepatic tumor, 1 hydatid cyst, 6 space occupying lesions of hepatic and biliary ducts, 2 extrahepatic masses, 7 hepatic hemangiomas and 1 liver cirrhosis. All the cases were proven by surgery, autopsy or pathology. The diagnostic accuracy was 85.9% and that of the liver cancer was 88%. The results suggested that the liver gamma imaging, being of high accuracy, safety, fast imaging and simplicity, be valuable in the diagnosis of the primary hepatocellular carcinoma and other intrahepatic space occupying lesions.
