摘要
目的比较MRCP与ERCP在探测胆系梗阻性病变中的准确性。方法收集经手术病理证实的胆系梗阻性病变28例,并将MRCP影像学图像与其ERCP图像对照分析。结果28例胆系梗阻性病例中,胆系结石7例,胆系肿瘤19例,其他胆系病变2例。MRCP检查全部成功,其图像与该患者ERCP图像极其相似,对胆系梗阻的显示成功率100%,均给予准确定位,确定梗阻病因的准确性为82.14%(23/28);对ERCP检查失败或显示不佳的病例,MRCP获得了较为满意的诊断信息。结论MRCP可对胆系梗阻性病变进行准确定位和较好的定性诊断。其无创、安全可靠,可作为胆系梗阻性病变的首选检查方法。
Objective To compare the accuracy of magnetic resonance cholangiopancreatography （MRCP）versus endoscopic retrograde cholangiopancreatography（ERCP）for detecting the biliary obstruction. Methods Twenty -eight patients with surgically and pathologically proved biliary obstructions underwent the both examinations of MRCP and ERCP. The imaging data oblained from both examinations were comparatively analyzed. Results 28 patients who comprised 7 cholelithiases, 19 tumors and 2 other lesions were successfully revealed by MRCP, while whose MRCP images were comparable to ERCP images. The successful rate and localized accuracy of MRCP in the visualization of biliary obstructions were 100 %. The accuracy of MRCP for diagnosing the obstructive causes was 82. 14 % （23/28）, even MRCP could obtain more satisfactory informations than ERCP. Conclusion MRCP can accurately define the obstructive sites and can identify the obstructive causes and MRCP is a noninvasive , safe and reliable examination so that it should be the first choice to diagnose the biliary obstruction.
