The liver scintigrams with colloidal radiogold were statistically observed in 184 cases which were clinically and pathologically confirmed to be liver cirrhosis(85), hepatoma(47), liver abscess(15), hepatitis(15), metastatic carcinoma(6) and other liver diseases(16) at Sacret Heart Hospital. The obtained results were as follows: 1. Enlargement of the liver was commonly present in the diseased liver, particularly the cases with space occupying lesion. The diminution in size of the right lobe of the liver was most commonly seen in the liver cirrhosis. 2. Irregular distribution of the radioactivity,“mottling”pattern was seen in the majority of liver cirrhosis (82%), and other diseases also showed high appearing percentage of“mottling”(20-55%). The border of scan image was irregular in about 77% of liver cirrhosis and hepatoma, but smooth in 80% of liver abscess. 3. The visualization of the spleen by the uptake of radioisotope was commonly noticeable in all patients with liver diseases, particularly in liver cirrhosis (85%). The frequency of spleen visualization was seemed to be influenced by the extent of involved parenchyme of the liver. 4. The margin of“cold area”was well demarcated in liver abscess (67%) and hepatoma (21%). The shape of“cold area”was spherical or hemispherical in liver abscess (74%) and amorphous in hepatoma (57%). 5. The definite findings of the specific liver disease were not demonstrated in this study, however, in many cases of liver cirrhosis there could be noted the shrinkage of the right lobe of the liver, irregular border of scan image, the nonuniform distribution of radioactivity in the liver and the increased uptake in the spleen and bone marrow.
