[en] To verify the value of CT in the diagnosis of cirrhosis, CRL ratio was measured in 225 Koreans who had and evidence of cirrhosis both clinically and radiologically. The mean value of CRL ratio was 0.68±0.21 which was significant different from the published value of normal person(0.45±0.07). The difference of CRL ratio between men and women and that among different age groups were found to be not statistically significant. CRL ratio of virus-related group(N=149) was 0.64±0.18, whereas that of virus-nonrelated group(N=76) was 0.76±0.23. There was a statistically significant difference of CRL ratio between virus-related group and virus-nonrelated group. CRL ratio of hepatoma-related group(N=113) was 0.71±0.22 whereas that of hepatoma-nonrelated group(N=112) was 0.66±0.19. There was no statistically significant difference of CRL ratio between hepatoma-related group and hepatoma-nonrelated group. Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver
