Fifty-three histologically proved cases of various diffuse liver diseases were studied on their computed tomography numbers (CTN). The machine used was the Ohio Nuclear's Delta Scanner 50 FS type and CTN was expressed by the Hounsfield unit (H). The mean was 66.6±2.6 H for normal control (N), 63.3±6.0 H for chronic hepatitis (CH), 61.8±7.0 H for liver cirrhosis (LC), 44.4±10.6 H for fatty infiltration (FI). There were no significant differences among them except FI group. As N group were all above 60 H and CH and LC groups were all above 50 H, CTN below 60 H could suggest chronic liver disease or fatty infiltration and CTN below 50 H could strongly suggest fatty infiltration. In eleven case; where total lipid content of the liver could be biochemically determined by the sulfo-phospho-vanillin reagent, a relation of total lipid content to CTN was studied. As a result, a significant correlation existed between them (r= —0.89; p< 0.001). If the diagnostic criterion for the fatty liver was set at total lipid content above 100 mg/g wet liver, CT criterion was estimated at CTN below 48 H from the regression formula.
