摘要
目的比较钆贝葡胺(Gd-BOPTA)CE-MRC与3D-SPACE-T2WI-MRC对活体肝移植供体胆管解剖及变异的显示。方法 32名肝移植供体,术前接受Gd-BOPTACE-MRC与3D-SPACE-T2WI-MRC。以术中胆管造影为标准,分析并比较两种方法诊断胆管变异情况。结果两种方法对胆总管、肝总管、左肝管及右肝管的显示差异有统计学意义(P<0.05),CE-MRC优于3D-SPACE-T2WI-MRC;对胆囊管,左前、后肝管,右前、后肝管及3级以上胆管的显示差异无统计学意义(P>0.05)。术中胆管造影诊断胆管变异17例,3D-SPACE-T2WI-MRC诊断14例,CE-MRC诊断15例,两者联合诊断17例。结论 3D-SPACE-T2WI-MRC与CE-MRC均可用于评估术前肝移植供体胆管解剖,CE-MRC对部分胆管的显示优于3D-SPACE-T2WI-MRC,二者联合应用效果更佳。
Objective To compare 3D-SPACE-T2WI-MRC with Gd-BOPTA contrast enhanced MRC （CE-MRC） for evaluation on biliary anatomy and variation in liver transplant donor candidates. Methods Totally 32 healthy liver transplant donor candidates underwent CE-MRC and 3D-SPACE-T2WI-MRC. According to intraoperative cholangiography,the diagnosing ability of biliary variation were analyzed and compared between two methods. Results CE-MRC provided a superior visualization of the common bile duct,hepatic duct,left hepatic duct and right hepatic duct than 3D-SPACE-T2WI-MRC did （P〈0.05）,whereas no difference was found in displaying of the cystic duct,left anterior and posterior segment duct,right anterior and posterior segment duct and bile duct above the third grade branches between the two methods （P〉0.05）. Biliary variation was proved with intraoperative cholangiography in 17 cases,14 of them were diagnosed with 3D-SPACE-T2WI-MRC,15 with CE-MRC,while all were diagnosed correctly with combining application of these two methods. Conclusion 3D-SPACE-T2WI-MRC and CE-MRC can be both used to evaluate biliary anatomy of liver transplant donor candidates,CE-MRC is superior to 3D-SPACE-MRC in display of part of the bile duct. The effect of combining application of these two methods is much better.
