摘　　要：目的 探讨胆道蛔虫病（biliary ascariasis,BA）的MRI及磁共振胰胆管成像（MR cholangiopancreatography,MRCP）的表现,提高胆道蛔虫病的影像诊断准确率.方法 回顾分析经临床及影像学检查确诊的9例BA患者的MRI及MRCP表现.结果 9例BA均呈条状,其中8例位于胆囊,病变T1WI上呈稍高信号,T2WI上呈低信号,3例表现为低信号中央见线状稍高信号,如＂三线＂征,8例MRCP上胆囊内见条状充盈缺损;1例蛔虫位于肝总管及胆总管,T1WI及T2WI未见显示,MRCP上肝总管及胆总管内见细条状低信号充盈缺损.结论 BA的MRI 及MRCP 表现具有特征性,依据其可做出明确诊断.Objective To investigate MR imaging mid MR cholangiopancreatography（MRCP） features of hiliary ascariasis（BA）, so that to improve the knowledge of this disease. Methods MRI and MRCP findings of 9 cases wilh BA verified by clinic and imag ings were retrospectively analyzed. Results At MR imaging, BAs appeared as strip in all cases, among them, 8 BAs located in gall bladder, the lesions were slightly hyperintense on TI WI and hypointense on T1 WI, linear slightly hyperintense were showed in the central of the hypointense on T1WI in 3 cases, like as three parallel lines, 8 BAs were seen as strip hypointense filling defect in gallbladder on MRCP. 1 BA located in common hepatic duct and commom hile duet,which did not show by T1 WI and ＂T2WI, while a strip hypointense filling defect on MRCP was detected. Conclusion MRI and MRCP manifestations of BA are characteristic, the di agnosis can be identified based on MRI and MRCP appearances.
