摘要 目的评价超声、CT、磁共振胆胰管成像(magnetic resonance cholangiopancreatography,MRCP)与内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatography,ERCP)对胆总管结石的诊断价值。方法回顾性分析2006年1月至2010年1月在北京大学人民医院行ERCP的患者256例,选取同时行超声、CT、MRCP检查的107例,以ERCP为诊断胆总管结石的"金标准"进行统计分析。选取经ERCP诊断为结石,且行MRCP检查的80例,按结石大小(<0.5cm、0.5~1.0cm、>1.0cm)分析MRCP诊断率。结果超声、CT、MRCP结果分别与ERCP结果行Kappa检验,P值分别为0.279、0.693、0.744,超声、CT、MRCP的敏感度分别为40.84%、82.19%、87.67%,特异度分别为96.88%、93.75%、90.63%。另外,分析不同大小的结石MRCP的诊断率为75.00%、94.44%、92.86%,三者差异无统计学意义(P>0.05)。结论诊断胆总管结石时,MRCP与ERCP两者诊断的一致性较好,其灵敏度及特异度均较高,不受结石大小的影响。
