摘　　要：采用 Ｐｈｉｌｉｐｓ Ｇｙｒｏｓｃａｎ Ｔ５ － Ⅱ型０ ．５ Ｔ 超导磁共振成像仪，体部包裹线圈，快速自旋回波序列重 Ｔ２ 加权扫描和最大强度投影算法重建图像。对２５ 例正常志愿者和７２ 例胆胰病变患者作磁共振胆胰管造影（ Ｍ Ｒ Ｃ Ｐ） 检查。并对 Ｍ Ｒ Ｃ Ｐ、 Ｕ Ｓ、 Ｃ Ｔ和 Ｅ Ｒ Ｃ Ｐ进行对比分析。结果说明，中场强 Ｍ Ｒ 机 Ｍ Ｒ Ｃ Ｐ 能清楚显示肝外胆道结构和扩张的肝内胆管。其对胆道结石、胆道肿瘤的敏感性、特异性和正确性均较高。其定位、定性准确率高于 Ｕ Ｓ，比 Ｅ Ｒ Ｃ Ｐ成功率高。healthy volunteers and 72 patients with various pancreaticobiliary diseases were examined by MRCP using a heavily T 2-weighted turbo spin-echo sequence and body-wrap-around coil technique on a 0.5T superconduction MR unit (Philips Gyroscan T 5-Ⅱ ) and images were postprocessed using maximun intensity projection (MIP) reconstruction. The Comparative analysis on function was conducted among MRCP, US, CT and ERCP. The results revealed that MRCP on middle magnetic field intensity MR unit was able to clearly show the structure of biliary ducts outside the liver and the expanded biliary ducts inside the liver. MRCP had high sensitivity, specificity and accuracy in diagnosing bile duct stones and tumors. The accuracy rate of location obtained by using MRCP was higher than that by using US and ERCP and it was easier to conduct successfully than ERCP.
