MRCP与ERCP、PTC诊断胆道梗阻性疾病的对比研究

A Comparative Study on MRCP and ERCP, PTC in the Diagnosis of Biliary Obstruction

目的 :探讨磁共振胰胆管成像 (MRCP)加梗阻部位薄层扫描或增强扫描、内镜逆行胰胆管造影 (ERCP)、经皮肝穿刺胆道造影 (PTC)对胆道梗阻的诊断价值。材料和方法 :回顾性分析 42例临床怀疑胆道梗阻患者的MRCP资料 (包括薄层或增强扫描 ) ,并与 18例ERCP、9例PTC比较 ,所有病例均经手术病理证实。结果 :MRCP加梗阻部位薄层扫描或增强扫描对胆管梗阻诊断准确率为 90 .5 % ,ERCP为 88.9% ,PTC为 88.9%。结论 :MRCP加梗阻部位薄层扫描或增强扫描对胆管梗阻具有重要诊断价值。

Purpose:To investigate the diagnostic value of magnetic resonance cholangiopancreatography(MRCP) with thin slices scan or contrast enhancement scan,endoscopic retrograde cholangiopancreatography(ERCP) and percutaneous transhepatic cholangiography(PTC ) in detection of biliary obstruction. Materials and Methods:The MRCP data(thin slices scan or contrast enhancement scan) of 42 cases suspected biliary obstruction were studied and compared with ERCP which was performed in 18, PTC which was performed in 9. All cases were confirmed by operation and pathology. Results:The diagnostic accuracy rate of MRCP with thin slices scan or contrast enhancement scan was 90.5%, that of ERCP was 88.9% and PTC was 88.9%. Conclusion:MRCP with thin slices scan or contrast enhancement scan is valuable in diagnosis of biliary obstruction.
