活体肝移植供体胆管造影——磁共振胆管水成像和莫迪司增强胆管造影对比

目的对比磁共振胆管水成像（T2WI—MRC）和莫迪司对比增强磁共振胆管造影（CE—MRC）对肝移植供体的胆管显示的差别。方法32例肝移植供体，其中男性18例，女性14例，年龄21～63岁，平均年龄35岁。术前行MRC水成像和莫迪司增强后胆管造影检查．对两种检查方法显示肝内外胆管的优缺点进行比较。所有肝移植供体均行术中胆管造影检查。结果2种方法均可清楚显示3级肝内胆管．但T2WI—MRC显示肝内3级以上胆管明显优于CE—MRC（P〈0．05）。T2WI—MRC有5例（15．6％）供体肠道内液体影响胆管显示．CE—MRC则无一例供体肠道液体影响胆管显示。呼吸引起的运动伪影两种检查方法均不明显。胆管变异9例，两种检查方法均正确诊断。2例供体T2WI—MRC显示胆总管不连续，CE—MRC及术中胆管造影显示胆总管正常。结论T2WI—MRC和CE—MRC均可用来评估术前活体肝移植供体胆管解剖，两种检查方法各有优缺点．联合应用将明显提高其诊断准确性。

Comparison of conventional T_2-weighted MR cholangiography with Multihance contrast-enhanced MR cholangiography in evalution of biliary anatomy of liver transplant donor candidates

Objective To compare conventional T2-weighted magnetic resonance cholangiography(T2WI-MRC) with Multihance-enhanced T1-weighted magnetic resonance cholangiography(CE-MRC) for evalution of biliary anatomy in liver transplant donor candidates.Methods A total of 32 healthy liver transplant donor candidates,male 18,female 14,aged 21-63 years,mean age 35 years,were examined with two kinds of MR cholangiographic methods.For T2WI-MRC,the three-dimensional turbo spin-echo sequence and oblique coronal heavily T2-wei...
