摘　　要：目的比较内镜逆行胰胆管造影(ERCP)和磁共振胰胆管造影(MRCP)对胆道恶性梗阻性疾病的诊断价值。方法对383例胆道梗阻,经手术和(或)ERCP病理证实的142例恶性胆道梗阻患者ERCP和MRCP影像资料进行对比分析。结果MRCP和ERCP总确诊137例恶性梗阻,占96.4%;两种方法定位诊断率分别为92.3%和87.3%;定性诊断率为78.5%和89.8%。结论MRCP在诊断胆道恶性梗阻性疾病方面具有简便安全以及漏诊率低等优点,但误诊率较ERCP高;而ERCP如在诊治过程中与MRCP相结合注重影像学的诊断分析,则可以提高阳性检出率。两者结合使用可起互补作用。Objective Comparing the diagnostic values for the malignant obstruction diseases of biliary tract between endoscopic retrograde cholangiopancreatography （ERCP）and MR cholangiopancreatography （MRCP）. Methods Parallel analysis for the ERCP and MRCP data of 142 malignancies confirmed by surgery and/or ERCP among 383 biliary tract patients was retrospectively carried out. Results MRCP and ERCP were performed with exploration of 137 cases, showing the total conformity of 96.4%; together with localization conformities of 92.3% and 87.3%, qualitative conformities of 78.5% and 89.8% respectively. Conclusions In diagnosing the malignant obstructing disease of biliary tract, MRCP has the advantages in convenience, safety and low false negative, but with higher false positive than ERCP; however, if combined with ERCP can get higher positive conformity.
