摘要
目的:探讨磁共振胆胰管造影(MRCP)诊断小儿胆道疾病的临床应用价值。材料和方法:回顾性分析60例胆道疾病患儿的MR I和磁共振胆胰管成像(MRCP)表现。结果:新生儿肝炎8例,其肝内、外胆管通畅。新生儿胆道闭锁10例,未见完整肝外胆道显示,6例冠状位T2W I示肝门部限局三角形高信号影,4例门静脉周围增宽,肝门部条索状长T2信号。胆总管囊肿42例,其中Todan iⅠ型32例、Ⅱ型3例、Ⅳa型5例、Ⅴ型2例;20例显示胆胰管合流异常,其中胆-胰型13例,胰-胆型7例。结论:MRCP可以准确鉴别新生儿肝炎及先天性胆道闭锁引起的新生儿黄疸;可清楚显示胆总管囊肿及胆胰管异常合流形态。
Purpose: To evaluate the role of MR cholangiopancreatography (MRCP) in diagnosing biliary fract disorders of infants and children. Material and Methods: MRI and MRCP images were analyzed retrospectively in 60 cases infants and children suspected with biliary tract disorders. Results: The whole intra-and extra-hepatic bile duct was observed in all the 8 cases of neonatal hepatitis. For 10 cases of biliary atresia, the entire extra-hepatic bile duct could not be visualized while a triangular high signal area confined to the portal hepatis in 6 cases and peripotal thickening with irregularly high signal intensity in another 4 cases were observed. For 42 cases of choledochal cysts, MRCP not only helped to specify the anatomical type classification (Todani classification type Ⅰ 32 cases, type Ⅱ 3 cases, type Ⅳ. 5 cases, and type Ⅴ 2 cases) but also to demonstrated the anomalous junction of pancreaticobiliary duct (type Ⅰ of bile duct drained into pancreatic duct at a right angle 13 cases, type Ⅱ of pancreatic duct drained into bile duct at an acute angle 7 cases). Conclusion: Neonatal hepatitis and biliary atresia can be differentiated accurately through MRCP. MRCP can visualize the modality of choledochal cyst and the anomalous junction of pancreaticobiliary duct.
