非屏气MRCP对于胆道梗阻性疾病的诊断价值(附60例ERCP与MRCP比较)

目的：研究非屏气ＭＲＣＰ技术显示胆道病变的能力。方法：６０例胆道梗阻性疾病患者进行了前瞻性ＭＲＣＰ和ＥＲＣＰ检查。分析ＭＲＣＰ图像胆胰管显示情况，有无充盈缺损及梗阻，作出定性诊断，并与ＥＲＣＰ比较。结果：ＭＲＣＰ和ＥＲＣＰ分别显示了１００％和８８％的胆管结石。对肿瘤及其它胆道梗阻病变，ＭＲＣＰ显示病变部位和形态的作用与ＥＲＣＰ基本一致。总的定性诊断准确性ＭＲＣＰ为８５％，ＥＲＣＰ为８８％。结论：非屏气ＭＲＣＰ是诊断胆道梗阻性疾病的可靠方法。

Diagnostic Value of Non Breath hold MR Cholangiopancreatography for OBstructive Biliary Diseases:Comparison with Endoscopic Retrograde Cholangiopancreatography in Sixty Patients

Purpose:To study the ability to visualize and diagnose the obstructive diseases of pancreaticobiliary duct with a non breath hold MR Cholangiopancreatography (MRCP).Methods:Sixty non breath hold MRCPs were obtained in patients with obstructive biliary diseases and compared with Endoscopic Retrograde Cholangiopancreatography(ERCP). Analyzing the visualization of dilated pancreaticobiliary duct, filling defect, and the presence and site of obstruction. The overall diagnostic accuracies of both modalities also were compared. Results:MRCP and ERCP showed biliary duct stones in 100% and 88%, gallstones in 100% and 45%, respectively. All obstructions were identified by two modalities, their sites and characters were accurately visualized in most cases. The overall diagnostic accuracies of MRCP and ERCP were 85% and 88% ( P >0.05),respectively.Conclusion:Non breath hold MRCP is a reliable method for depiction of obstructive biliary diseases.
