摘　　要：目的　评价磁共振胰胆管成像 (MRCP)技术在胆胰系统疾病诊断中的应用价值。方法　 6 8例患者进行了MRCP检查 ,其中正常对照组 11例 ,各种胰胆管病变组 5 7例。扫描使用ELSCINTSGR 2 .0T超导磁共振成像仪 ,体线圈及呼吸门控触发技术。平扫采用自旋回波 (SE)常规成像 ;MRCP采用快速自旋回波 (FSE)重T2 加权像进行薄层扫描。所得图像用最大强度投影法 (MIP)进行三维 ( 3D)重建。结果　MRCP能清晰显示胰胆管的解剖结构 ,对胆道梗阻程度和梗阻部位判断的确诊率达 10 0 % ,梗阻原因的确诊率达 91.2 %。结论　MRCP检查的成功率高 ,胰胆管解剖结构显示清晰 ,适应于各种胰胆管疾病的诊断 。Objective To evaluate the clinical application value of MR cholangiopancreatography(MRCP) in diagnosis of biliopancreatic disease.Methods MRCP was performed in sixty-eight cases,including eleven normal contract group and fifty-seven patients with various pancreaticobiliary duct disease.Fast Spin-echo(FSE)was used for heavily T 2-weighted and maximum-intensity-projection (MIP)algorithm was made for three-dimensional(3D) reconstruction.Results MRCP can exhibit the structure of pancreaticobiliary duct and it's image were similar to those of direct cholangiopancreatography.The accaracy of MRCP in detection of the degree and location of bile duct obstruction was 100%.The accaracy of MRCP for evaluating the cause of obstruction was 91.2%.Conclusion This study shows the MRCP examination has a high success rate and can demonstrate pancreaticobiliary duct diseases.MRCP may provide an efficient alternative to direct cholangiopancreatography,especially when ERCP and PTC are unsuccessful or inadequate.
