摘　　要：目的：探讨磁共振胆胰管成像（ＭＲＣＰ）在临床上对不同胆胰管疾病的诊断价值。材料与方法：回顾分析２３例疑有胆胰管疾病患者的ＭＲＣＰ图像，并与其对照的ＥＲＣＰ或ＰＴＣ的诊断结果相比较。ＭＲＣＰ在１．０Ｔ超导磁场中完成。采用快速自旋回波序列和ＭＩＰ法重建。结果：２３例患者的ＭＲＣＰ成功率为１００％，１４例手术病例中，ＭＲＣＰ对胆胰管系统非肿瘤性病变和肿瘤性病变的诊断正确率分别为１００％和８３％，１例误诊。结论：ＭＲＣＰ在诊断胆胰管疾病方面简便、安全，无创伤性，无需造影剂，而且具有与ＥＲＣＰ、ＰＴＣ相同的诊断价值。Objective: To study the diagnostic value of MRCP in various biliary and pancreatic diseases.Materials and Methods:23 cases suspected to have biliary and pancreatic disease with MRCP examination were reviewed and analysed. The diagnostic results of MRCP were compared with that of ERCP or PTC. MRCP was performed with a 1.0 tesla superconductive magnetic field, and processed with turbo spin echo seqnence and maximum intensity projection algorithm to create images of the biliary tree and pancreatic duct.Results:MRCP images of diagnostic quality were obtained in all cases. The diagnostic accuracies of MRCP in benign and malignant lesions of biliary and pancreatic system were 100% and 83% respectively in 14 operative cases. Only one case was misdiagnosed.Conclusion: MRCP not only is simple, safe, noninvasive and not require contrast material in evaluating the biliary and pancreatic duct but also offers a diagnostic value equivalent to that of ERCP or PTC. It is likely to replace ERCP or PTC in many diagnostic fields.
