Abstract:
Objective To evaluate the role of MR imaging (MRI) and MR cholangiography (MRC) for the diagnosis of hepatic hilar cholangiocarcinoma (HHC) and assessment of tumor resectability. [WT5”HZ]Methods [WT5”BZ] MRI and MRC were performed in 280 patients with obstructive jaundice from Mar.1997 to May.1999. The diagnosis of HHC was proved in 38 cases (13 6%, 38/280) by laparotomy and pathology. Imaging features and classification as related to surgical therapy of the tumor were analyzed. [WT5”HZ]Results [WT5”BZ] Tumor was identified in 24 out of 38 HHC cases. The contrast enhancement scanning further found tumors in 8 out of 14 HHC cases,with a total rate of tumor finding of 84% (32/38). MRI also suggested hepatic metastasis in 4 cases, portal vein invasion in 7 cases. MRC found hilar obstruction and dilatation of the intrahepatic biliary tree in all HHC cases. The surgical resection rate was 24%(9/38) including 4 cases of typeⅠ,3 cases of typeⅡ,1 of type Ⅲa and 1 of typeⅢb. Resection was impossible or not worthwhile in cases with hepatic metastasis, invasion of portal vein and/or hepatic artery. Conclusion [WT5”BZ]MRI and MRC plays an important role in the diagnosis of hepatic hilar cholangiocarcinoma and assessment of tumor resectability.
