摘　　要：目的比较单次激发厚层投射磁共振胰胆管成像(SSFSE-MRCP)(包括梗阻部位薄层扫描或增强扫描)和内镜逆行胰胆管造影(ERCP)对梗阻性胆管疾病的诊断价值。资料与方法采用单次激发投射快速自旋技术,对51例临床怀疑胆管梗阻患者进行SSFSE-MRCP检查,并均行常规ERCP检查,对MRCP影像资料和ERCP进行对照分析,所有资料均经手术病理或ERCP检查证实。结果SSFSE-MRCP图像清晰,检查成功率高;MRCP对胆管梗阻定位准确率100%,定性准确率为78.4%,ERCP定性准确率为70.6%。结论MRCP安全、简便、无创伤,成功率高,对胆管梗阻疾病的定位诊断准确。结合ERCP检查,可提高胆管梗阻的定性诊断准确率。Objective To compare the diagnostic value of magnetic resonance cholangiopancreatography （MRCP） using single shot projection（ including thin slices scan or contrast enhancement scan） and endoscopic retrograde cholangiopancreatography （ERCP） in the detection of bile duct obstruction. Materials and Methods 51 patients with suspected bile duct obstruction were performed SSFSE MRCP and routine ERCP. The results of SSFSE MRCP were compared with that of ERCP. All cases were confirmed by surgery and pathology or ERCP. Results MRCP examination succeeded in all 51 patients and the pancreaticobiliary duct was shown satisfactorily. The accuracy of SSFSE MRCP in the detection of the degree and level of bile duct obstruction was 100%, and the diagnostic accuracy of SSFSE MRCP was 78.4%, the diagnostic accuracy of ERCP was 70.6 %. Conclusion SSFSE MRCP is not only simple and safe , but also invasive and effective, it can accurately define the level of bile duet obstruction. Combining with the routine ERCP, the specificity for the diagnosis of bile duct obstruction can be improved.
