磁共振胰胆管成像在胆道梗阻性疾病诊断中的应用

Magnetic resonance cholangiopancreatography in diagnosis of biliary obstructive diseases

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。

Abstract: 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.
