Computed Tomography in the Diagnosis of Fatty Liver: Total Lipid Content and Computed Tomography Number. Tohoku J. exp. Med., 1982, 136 (3), 337-342 - Fifty-three histologically proved cases of various diffuse liver diseases were studied for their computed tomography numbers (CTN). The machine used was Ohio Nuclear's Delta Scanner 50FS type and CTN was expressed by the Hounsfield unit (H). Mean CTN in each group was as follows: 66.6±2.6H in normal control (N), 63.3±6.0H in chronic hepatitis (CH), 61.8±7.0H in liver cirrhosis (LC), and 44.4±10.6H in fatty infiltration (FI). There were no significant differences among them except FT group. As N group were all above 60H and CH and LC groups were all above 50H, CTN below 60H suggests chronic liver disease or fatty infiltration and CTN below 50H strongly suggests fatty infiltration. In eleven cases 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 of fatty liver was set at total lipid content above 100mg/g wet liver, CT criterion was estimated at CTN below 48H from the regression formula. - fatty liver; computed tomography; computed tomography number; total lipid content
