MR Cholangiopancreatography in the diagnosis of infants and children with biliary tract disorders

目的 探讨磁共振胆胰管成像 (MRCP)在小儿胆道疾病诊断中的实用价值。方法 用TOSHIBAVISART ,1.5T(磁场强度 )磁共振机及相关软件和技术 ,检查新生儿肝炎 1例 ,肝外胆道闭锁 1例 ,胆总管囊性扩张 8例 ,胆道术后腹痛 2例。结果 新生儿肝炎者因麻醉欠佳而检查失败 ,肝外胆道闭锁者呈盲管状的胆总管及 2级肝管可辨 ;8例胆总管囊性扩张者均可见肝外胆道及 3级肝管、胰管及其立体构型 ;2例胆道术后腹痛者均查出病因。结论 MRCP同样适合小儿胆胰疾病的诊断 ,具有易施行、无放射、无创伤、无并发症 ,且图像清晰 ,可多方位显示自然状态下的胆管树三维构型 。

Objective To evaluate the roles of MR cholangiopancreatography (MRCP) in the diagnosis of infants and children with biliary tract disorders.Methods MRCP examinations were carried out in 12 patients:one infant with the neonatal hepatitis (NH),one infant with biliary atresia (BA),8 with congenital choledochal cyst (CCC),2 with recurrent postoperative epigastric pain (PEP).Results MRCP examination was failed in the NH group due to inadequate anaesthesia.A blind bile duct could be visualized in BA group.In all CCC patients,the dilated extrahepatic duct,the third grade of hepatic ducts and pancreatic ducts were clearly visible.The cause of the 2 patients with epigastric pain was confirmed.Conclusions MRCP displays the biliary tree and panceatic ducts clearly.It is a useful diagnostic technique in infants and children with biliary or pancreatic diseases.
