Abstract

PURPOSE
To evaluate the accuracy of preoperative segmental localization of hepatic lesion by conventional computed tomography(CT).
MATERIALS AND METHODS
Thirty nine masses of hepatocellular carcinoma in 36 patients were included in this study. We retrospectively compared the extent of involved segments by CT with that of surgery. In case of disagreement between CT and surgery, we classified as overestimation, underestimation and mismatch. And we calculated the accuracy of localization of each hepatic segments by CT. RESULT: The rate of agreement between CT and surgery was 61.5% (24/39). In cases of disagreement, we overestimated in 7 (18%), underestimated in 3 (7.7%), and made a mismatch in 5 (12.8%). Segment I, II and Ill showed the highest accuracy (100%), but segment VII showed the lowest accuracy (88.6%).
CONCLUSION
Preoperative localization of hepatic lesion in conventional CT is limited in sensitivity (61.5%), especially in the right lobe. Consequently other complementary studies such as dynamic CT and hepatic angiography are helpful for preoperative localization.
