摘要
目的:探讨磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)诊断胆道梗阻性疾病的价值及良、恶性梗阻性疾病的影像表现。方法:对45例胆道梗阻性疾病患者的MRCP和临床诊治资料进行回顾分析。结果:MRCP定位诊断准确率100.0%,定性准确率88.9%;胆道结石表现为胆管内充盈缺损、周围有胆汁包绕或为"杯口状"阻塞,胆管炎表现为胆管节段性扩张和狭窄,恶性病变表现为胆管突然截断或偏心性狭窄。结论:MRCP对胆道梗阻性疾病的诊断具有重要价值,应作为常规检查方法。
Objective：To explore the role of magnetic resonance cholangiopancreatography（MRCP） in diagnosis of biliary obstructive diseases and the imaging manifestations of benign and malignant lesions.Methods：The MRCP and clinical data of 45 patients with biliary obstructive diseases were analyzed retrospectively.Results：The diagnostic accuracy rate of MRCP was 100.0% for location and 88.9% for qualitation.The imaging manifestation of biliary stones was filling defects in the bile duct which was surrounded by bile or obstruction in the shape of a cup,cholangitis displayed a segmental dilation and stenosis of the bile duct,malignant lesions showed an abrupt occlusion or asymmetric narrowing in the bile duct.Conclusions：MRCP is of great value in diagnosis of biliary obstructive diseases and should be used as a routine examination means. 7
