摘　　要：目的 :探讨磁共振胰胆管成像 (MRCP)技术的临床价值。方法 :对 49例胰胆管病变的病人采用快速自旋回波之重 T2 加权技术进行 MRCP检查 ,经最大信号强度投影 (MIP)取得图像。2 0例有手术病理结果。结果 :MRCP图像与 ERCP、PTC图像相似 ,能较好地显示胰胆管疾病的病变部位、梗阻程度、狭窄和充盈缺损 ,准确性较高。结论 :MRCP作为一种安全非创伤性影像学诊断技术 ,不使用造影剂 ,能较好地显示胰胆管的解剖和病理变化 ,从而提高胰胆管疾病的诊断水平。Objective:To evaluate the value of clinical application of MR cholangiopancreatography(MRCP).Methods:49 patients with bile duct or pancreatic duct diseases underwent MRCP study,(i.e.hydrography of the ducts with heavily T 2 weighted FSE sequence and maximum intensity projection).Among them,20 cases were confirmed surgically and pathologically.Results:Images of MRCP were somewhat similar to those of ERCP and PTC,dipicting fairly well the site and length of narrowing or filling defect of the diseased duct.Conclusion:MRCP is a safe and nonivasive diagnostic imaging technique without the need of contrast agent for displaying the anatomy and pathological changes of the ducts so that to improve diagnostic liven.
