磁共振胆胰管造影联用动态增强对胆管癌的诊断价值

目的：评价屏气磁共振胆胰管造影(MRCP)及联合应用动态增强MRI对胆管癌的临床诊断价值。方法：回顾性分析88例经手术、病理证实的胆管癌的MRCP及动态增强MRI表现。结果：88例检查均一次成功，全部病例胆胰管显示满意。MRCP对肝门型胆管癌和肝外胆管型胆管癌的定位诊断准确率均为l00％，定性诊断准确率为100％和52．2％，结合动态增强MRI扫描，对肝外胆管型胆管癌定性诊断准确率提高到91．3％。结论：MRCP检查成功率高，对肝门型胆管癌和肝外胆管型胆管癌定位准确，结合动态增强MRI扫描，定性诊断也有较高准确性。

Clinical value of MR cholangiopancreatography combining with dynamic enhanced MRI in the detection of cholangiocarcinoma

Objective To evaluate the clinical value of breath-hold magnetic resonance cholangiopancreatography (MRCP) combining with dynamic enhanced MRI in the diagnosis of cholangiocarcinoma. Methods MRCP findings of 88 cholangiocarcinoma patients proved surgically and pathololgically were analyzed retrospectively. Results MRCP examination succeeded in all the 88 patients and the pancreaticobiliary ducts were shown satisfactorily. The accuracy of MRCP in the location of both hilar and extrahepatic cholangiocarcinoma was 100%, and the accuracy of detecting hilar and extrahepatic cholangiocarcinoma were 100% and 52.2%, respectively. Combining with dynamic enhanced MRI, the detecting accuracy of extrahepatic cholangiocarcinoma improved to 91.3%. Conclusions MRCP examination has a high successful rate and can accurately determine the location of hilar and extrahepatic cholangiocarcinoma, and the accuracy of qualitative diagnosis for the former two is high. Combining with dynamic enhanced MRI, the specificity of determining extrahepatic cholangiocarcinoma is also high.
