摘　　要：目的探讨肝内胆管囊腺瘤及囊腺癌的低磁场MRI表现及其病理学基础,评价低磁场MRI对其诊断价值。方法搜集7例以手术病理证实的肝胆管囊腺瘤及囊腺癌病例。5例作常规扫描,2例平扫及增强扫描。回顾性分析7例肝胆管囊腺瘤及囊腺癌的低磁场MRI表现,与病理结果相对照。结果6例胆管囊腺瘤,1例胆管囊腺瘤。7例均为多囊,囊壁、分隔光整,有的囊壁、分隔增厚。均可见壁结节或乳头状突起。囊内为液体成份信号,两例可见3种T1WI、T2WI信号。结论低磁场MRI可显示肝胆管囊腺瘤及囊腺癌的一些特征性表现,但难于鉴别良性肝胆管囊腺瘤与囊腺癌,其定性诊断主要依靠病理。Objective To evaluate the Low Field MR1 features and the pathologic basis of intrahepatic biliary cystadenoma and cystadenocarcinoma, Methods seven cases of biliary cystadenoma and cystadenocarcinoma were collected. All cases were conformed by operation and pathology, Plain scan were performed in five cases. Plain scan and enhanced scan were performed in two cases. The Low Field MRI features of seven cases of biliary cystadenoma and cystadenocarcinoma were analyzed retrospectively and correlated with the pathologic findings, Results Six cases were biliary cystadenoma and one was canceration from the biliary cystadenoma. All of seven cases were multilocular fluid cystic mass and had mural nodules and/or papillary excrescences, Thickening of internal septa were shown in some cases and three genus imagess of WTI1 WTI2 were shown in two cases. Conclusions LOw Field MRI scan reveal the some characteristic features of biliary cystadenoma and cystadenocarcinoma. But differentiation between biliary cystadenoma and cystadenocarcinoma is still difficult on LOw Field MRI scan. The diagnoses with nature mostly depend on pathology.
