摘要
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 This work was done to compare the validity of various imaging methods, eg. ultra-sonography (US), computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), and, especially, magnetic resonance cholangiopancreatography (MRCP) for extrahepatic bile duct carcinoma.Methods Sixty-five such patients who were operated and confirmed by pathology were used. Sixty patients had been examined by US; 52 by CT; 20 by ERCP; 9 by PTC and 20 by MRCP. The results of these imaging methods were compared with those of operative and pathological findings.Results The diagnostic accuracy rates of site location were US 81.7%, CT 84.6%, ERCP 75.0%, PTC 88.9% and MRCP 100%, respectively. The quality diagnostic accuracy rates were US 73.3%, CT 82.7%, ERCP 75.0%, PTC 88.9% and MRCP 95.0%, respectively.Conclusion MRCP is superior to US? CT ? ERCP and PTC not only in demonstrating the position but also the nature of extrahepatic bile duct carcinoma.
