目的 通过肝外胆管癌的影像学诊断 ,探讨MR胆胰管造影 (MRCP)对肝外胆管癌的诊断价值。方法 6 5例经手术病理证实的肝外胆管癌 ,其中行超声波检查 (US) 6 0例 ,电子计算机断层扫描 (CT) 5 2例 ,逆行胰胆管造影 (ERCP) 2 0例 ,经皮肝穿刺胆管造影 (PTC) 9例 ,磁共振胆胰管造影(MRCP) 2 0例。根据各种检查方法显示的影像学表现和诊断 ,与手术病理结果进行对照分析。结果定位诊断准确率US为 81.7% ,CT为 84.6 % ,ERCP为 75 .0 % ,PTC为 88.9% ,MRCP为 10 0 % ;定性诊断准确率US为 73.3% ,CT为 82 .7% ,ERCP为 75 .0 % ,PTC为 88.9% ,MRCP为 95 .0 %。结论 MRCP对肝外胆管癌诊断定位和定性优于US、CT、ERCP及PTC。
Objective To evaluate the diagnostic value of MR cholangiopancreatography (MRCP) in extrahepatic cholangiocarcinoma by imaging diagnosis of extrahepatic cholangiocarcinoma. Methods Totally 65 patients with extrahepatic cholangiocarcinoma confirmed by surgery and pathology were included in our study. Ultrasound (US) 60, computed tomography (CT) 52, retrograde cholangiopancreatography (ERCP) 20, percutaneous liver Puncture and cholangiography (PTC) in 9 cases, magnetic resonance cholangiopancreatography (MRCP) 20 cases. According to various examination methods showed imaging findings and diagnosis, and surgical pathology results were analyzed. Results The accuracy of localization diagnosis was 81.7% for CT, 84.6% for CT, 75.0% for ERCP, 88.9% for PTC, and 10% for MRCP. The accuracy rate of qualitative diagnosis was 73.3% for US and 82.7% for CT. ERCP 75.0%, PTC was 88.9% and MRCP was 95.0%. Conclusion MRCP is superior to US, CT, ERCP and PTC in the diagnosis and localization of extrahepatic cholangiocarcinoma.
