MRI多序列结合MRCP对肝内胆管结石并胆道梗阻的诊断价值

目的探讨MRI多序列扫描结合MRCP在肝内胆管结石并胆道梗阻诊断中的价值。方法回顾性分析2013年1月至2016年5月在本院进行了MRI影像检查并经手术病理确认的50例肝内胆管结石并胆道梗阻患者的临床和影像资料,同时对结石的影像表现、分布及其他临床表现进行归类分析。结果 MRI多序列扫描结合MRCP对于肝内胆管结石并胆道梗阻的整体确诊率为94%。对不同位置结石确诊率为:肝左叶确诊率96.7%;肝右叶患者确诊率87.5%;左右肝内胆管均有结石确诊率91.7%,诊断结果与手术确认结果相比,差异无统计学意义(P0.05)。结论 MRI多序列扫描结合MRCP对于肝内胆管结石并胆道梗阻的诊断具有较高的准确率,对临床手术治疗能起到较好的指导作用。

Diagnostic Value of Intrahepatic Bile Duct Stones and Bile Duct Obstruction using MRI Multi-sequence Imagin Combined with MRCP

Objective To investigate the value of MRI multi-sequence scanning combined with MRCP in the diagnosis of intrahepatic bile duct stones and bile duct obstruction. Methods To analyze the MRI and MRCP images of 50 patients with intrahepatic cholangiolithiasis with the obstruction of biliary identified by surgery from Jan 2013 to May 2016 in our hospital. Then classify and analyse of the imaging manifestations and other clinical manifestations of stones. Results The overall diagnostic rate of MRI multi-sequence scan combination with MRCP for intrahepatic cholangiolithiasis with the obstruction of biliary tract was 94%. The diagnosed rate of the different location:the left hepatic lobe diagnosed rate was 96.7%;the right lobe of liver in patients was 87.5%. The diagnosis rate of both left and right intrahepatic cholangiolithiasis was 91.7%. The diagnosis results were compared with the results of surgery confirmation, there is no statistically significant difference(P<0.05). Conclusion MRI multi sequence scan combined with MRCP has a high accuracy rate in the diagnosis of intrahepatic bile duct stones and bile duct obstruction, which can guide role in the clinical treatment well.
