摘　　要：目的:评估高分辨MR多序列成像结合磁共振胆胰管成像(MRCP)、仿真内窥镜技术(MRVE)对胆道梗阻性疾病的临床诊断价值。方法:对56例临床疑诊胆道梗阻性疾病的患者,使用3.0T MR多序列成像并联合MRCP、MRVE重建。将术前影像诊断结果和术后随访资料进行比较。结果:56例患者中有6例胆管炎合并狭窄、29例是胆管结石、4例是胰腺头部肿瘤、5例是壶腹部肿瘤、12例是胆管肿瘤,高分辨MR多序列成像融合MRCP、MRVE对胆道梗阻性疾病的整体确诊率为91.1%,诊断结果与手术和随访确认结果相比,差异无统计学意义(P<0.05)。结论:高分辨M R多序列成像结合MRCP、MRVE可较好地显示胆管梗阻的部位、外部形态、内部结构,对胆道梗阻性疾病的诊断具有较高的准确率,该技术的应用将为临床手术方式的选择和预后评估提供更为详尽的影像解剖依据,为临床手术治疗能起到较好的指导作用。Objective To evaluate the clinical value of high-resolution magnetic resonance imagingin(High-resolution MRI)+(Magnetic Resonance Cholangiopancreatography,MRCP),(Magnetic Resonance Virtual Endoscopy,MRVE)in the diagnosis and treatment of biliary obstructive lesions while Methods 56 patients with pathology proven biliary obstructive lesions while were examined with routine High-resolution MRI,Virtual endoscopy.the series of cases were classified and the deta were also compared with surigical findings.Results 6 were diagnosed with bile duct inflammation,29 were diagnosed with common bile duct stones,4 were diagnosed with tumor of the head of the pancreas,5 was diagnosed with ampullary tumor,12 were diag-nosed with bile duct tumor,The overall diagnostic rate of High-resolution MRI multi-sequence scan combination with MRCP+MRVE for biliary obstructive lesions while of biliary tract was 91.1%.The diagnosis results were compared with the results of surgery confirmation,there is no statistically significant difference(P﹤0.05).Conclusion High-resolution MRI multi sequence scan combined with MRCP+MRVE has a high accuracy rate in the diagnosis of biliary obstructive lesions while bile duct stones and bile duct obstruction,which can be us ed as a conventional preoperative examination.the can accurately demonstrate the primary tracts biliary obstructive lesions while and is valuable in treatment and surgery planning.can effectively improve the cure rate of biliary obstructive lesions while,reduce the recurrence rate,which can guide role in the clinical treatment well.
