[摘要] 目的 探讨磁共振胰胆管成像(magnetic resonance cholangiography,MRCP)在恶性胆道梗阻中的应用价值。方法 对74例经手术病理或临床治疗证实的恶性胆道梗阻性病例，回顾性分析其影像学表现及与临床病理的关系。所有病例均做MRCP检查，采用单次激发放射状自旋回波序列技术。其中胆囊癌2例，肝门转移癌7例，胆管癌49例，胰头癌16例。结果 本组74例MRCP检查均一次成功，肝内外胆管显示率100%。MRCP定位诊断准确率为93.2%，定性诊断准确率为89.2%。结论 MRCP是一种无创性的有效检查手段，能清晰显示正常或异常的胰胆管结构，定位和定性诊断准确率高，能为临床提供十分有意义的诊断资料。[关键词] 恶性胆道梗阻；胰胆管成像；磁共振成像

[Abstract] Objective To evaluate the clinical diagnostic value of magnetic resonance cholangiopancreatography(MRCP) in diagnosis of malignant biliary obstruction,and their value in differential diagnosis. Methods MRCP data of 74 cases of malignant biliary obstruction proved by surgical pathology and clinical result were analyzed retrospectively,MRCP was performed using singleshotradio SE sequence on all 74 cases.Of all cases included primary gallbladder carcinoma in 2,metastases in 7,cholangiocarcinoma in 49,carcinoma of head of pancreas in 16. Results MRCP was succeeded at one time in all cases.On MRCP,the visual rate of intrinsic and extrinsic hepatic bile duct was 100%.The localized and qualitative diagnosis of lesions were up to 93.2%,89.2% retrospectively. Conclusion MRCP is a noninvasive technique for depicting the normal and abnormal pancreaticobiliary duct,and if had the excellent accuracy in the determination of the locations and causes. ......
