Stage of chronic liver disease has been reported to be assessable by a combination of several ultrasonographic (US) findings. Of these, dullness of the liver edge, roughness of the liver parenchyma, narrowing of the hepatic vein, and splenomegaly are reported as the most useful. We calculated liver-index (L.I.) by assigning one point to each of these four US findings when they were positive, and summing the point in each case. We then assessed the relationship between L.I. and pathologic stage, laboratory data, and duration of type C chronic diseases. The relationship between L. I. and pathologic stage of type C chronic liver disease was close, and L.I. was significantly correlated to ICGR=15, Type IV collagen, and platelet count. L.I. also tended to be greater in patients in whom disease duration was longer. L. I. is thus useful when evaluating development of type C chronic liver diseases.
