Caudate to Right Lobe Ratio of Liver Cirrhosis in Korean by Computed Tomography

PURPOSE: 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. MATERIALS AND METHODS: The mean value of CRL ratio was 0.68±0.21 which was significant difterent 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 signficant. RESULTS: 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 heparoma-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. CONCLUSION: Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver.
