摘要 目的 :评价比较磁共振胰胆管成像 (MRCP)二维高级快速自旋回波 (2DFASE)序列和三维高级快速自旋回波(3DFASE)序列对胆道术后胰胆管系统的显示及图像质量评估。方法 :对 72例胆道术后出现不明原因发热、黄疸、肝功能异常、右上腹痛等症状的患者同时行MRCP的两种序列检查 ,并分别与手术、直接胆道造影图像进行对照。结果 :MRCP的这两种序列均能很好显示术后胰胆管系统解剖 ,3DFASE序列显示肝内一、二级胆管优于 2DFASE序列 ,但差异无显著性意义 (P >0 .0 5 ) ;3DFASE序列显示胰管优于 2DFASE序列 ,差异有显著性意义 (P <0 .0 5 )。MRCP两种序列均获得了较好的图像 ,两种序列图像质量差异无显著性意义 (P >0 .0 5 )。结论 :MRCP 3DFASE序列较 2DFASE序列更适于胆道术后胰胆管系统的检查。 Objective:To evaluate and compare the performance of two pulse sequences commonly used at magnetic resonance (MR) cholangiopancreatography in the demonstration of postoperative cholangiopancreatic anatomy.Methods:MR cholangiopancreatography was performed in 72 patients who developed an unexplained fever,right upper quadrant abdominal pain and jaundice after surgery of the biliary ductal system.The image quality of 2D fast advanced spin-echo (2D FASE) sequence and 3D fast advanced spin-echo (3D FASE) sequence was compared.The results of the two pulse sequences were correlated with surgical findings and direct cholangiography.Results:Postoperative anatomy of pancreatic and biliary ducts could be well demonstrated with both 2D and 3D FASE sequence.3D FASE could better demonstrate intrahepatic biliary ducts than 2D FASE,but there was no significant difference (P>0.05).For demonstration of pancreatic duct,3D FASE was superior to 2D FASE,and the difference was significant (P<0.05).Conclusion:The 3D FASE sequence is more applicable than 2D FASE sequence for examination of the postoperative cholangiopancreatic system.
