Correlation between the blood clearance half time and findings of liver scan using the colloidal radiogold in patients of liver cirrhosis is observed through the scoring system, in which the more changes in size, shape and density in the liver scan, the more points are given (table 1). Results:1) Within the increase in severity of hepatocellular dysfunction in liver cirrhosis, the degree and frequency of following changes in liver scan (done with colloidal radiogold) were increased in order. a) generalized hepatomegaly b) enlargement of th left lobe & reduction of the right lobe c) relatively increased radiodensity in the left lobe and d) visualization of spleen. 2) Frequency of the normal scan in liver cirrhosis was 12¡¾3.56%, frequency of normal value in blood clearance half time of the radiogold was 5.0¡¾2.34% and frequency of normal scan & normal blood clearance rate in liver cirrhosis was 3.6¡¾2.06%.
