磁共振胰胆管成像在胆道结石诊断中的应用价值

Effectiveness of Application of Magnetic Resonance Cholangiopancreatography in Diagnosis of Biliary Calculi

目的探讨磁共振胰胆管成像（MRCP）技术在胆道结石诊断中的应用价值。方法回顾性分析2012年3月~2012年8月于我院经内镜下逆行胰胆管造影术（ERCP）确诊的60例胆道结石患者的MRCP资料。结果 ERCP共发现肝外胆管结石19例,肝内胆管结石12例,肝内外结石29例;MRCP共发现肝外胆管结石19例,肝内胆管结石10例,肝内外结石27例,漏诊4例,诊断符合率为93.3%,漏诊率为6.7%。结论 MRCP诊断胆道结石具有安全、简便、无创等特点,且诊断符合率较高,值得推广。

Objective To evaluate the effectiveness of application of MRCP（Magnetic Resonance Cholangiopancreatography） in the diagnosis of biliary calculi.Methods The MRCP images of sixty biliary calculi patients who had been confirmed by using ERCP（Endoscopic Retrograde Cholangio-Pancreatography） in the hospital from March to August 2012 were retrospectively reviewed.Results Among all the patients,19 cases of extrahepatic bile duct stones,12 cases of intrahepatic bile duct stones as well as 29 cases of liver and extrahepatic stones were found by using ERCP versus 19,10 and 27 cases respectively by using MRCP.MRCP failed to diagnose four cases and its diagnostic accuracy and missed diagnosis rate were 93.3% and 6.7% respectively.Conclusion MRCP demonstrated its safe,simple and noninvasive features with high success rate,which deserved wider promotion.
