摘　　要：目的对比钆贝葡胺增强胆道成像(CE-MRC)和磁共振胆道水成像(T2WI-MRC)对活体肝移植术后胆道并发症的诊断价值。方法 56例活体肝移植术后,均行CE-MRC和T2WI-MRC,对比其对活体肝移植术后胆道显示及胆道并发症的诊断价值,所有诊断均经临床证实。结果 56例患者,MRC水成像53例(94.64%)胆道显示良好,增强胆道成像46例(82.14%)胆道显示良好,胆道显示水成像优于增强胆道成像,差别具有统计学意义(χ2=4.264,P<0.05)。胆道狭窄27例,MRC水成像准确诊断21例(77.78%),增强胆道成像准确诊断26例(96.30%),胆道狭窄诊断增强胆道成像优于水成像,差别有统计学意义(χ2=4.103,P<0.05)。结论 T2WI-MRC和CE-MRC诊断活体肝移植术后并发症联合应用效果更佳。Objective To compare gadobenate dimeglumine-enhanced magnetic resonance cholangiography（ CE-MRC） with conventional T2 -weighted magnetic resonance cholangiography（ T2 WI-MRC） for evalution biliary complication after living donor liver transplantation（ LDLT） . Methods Fifty-six patients after LDLT were examined with CE-MRC and T2 WI-MRC methods. The diagnostic value of the two methods to depiction of biliary and complication was compared. All diagnosis were confirmed by clinic. Results Among all fifty-six patients,biliary imaging quality of fifty-three patients were good in T2 WI-MRC,and biliary imaging quality of fourty-six patients were good in CE-MRC. T2 WI-MRC was superior to CE-MRC and there was significant difference（ χ^2 = 4. 264,P 〈0. 05） . Twenty-seven patients had biliary stricture,twenty-one patients had been made a definite diagnosis by T2 WI-MRC,twenty-six by CE-MRC. In the diagnosis of biliary stricture,CE-MRC was superior to T2 WI-MRC and the difference had statistical significance（ χ^2 = 4. 103,P〈0. 05） . Conclusion The combined application of T2 WI-MRC and CEMRC has a better effect in the diagnosis of biliary complication after living donor liver transplantation.
