1、临床放射学杂志2014年第33糯第3期·377·腹部放射学MRI评价肝尾状叶静脉：Budd—Chiari综合征患者与正常人群对照研究唐伟，张小明，翟昭华，曾南林【摘要】目的探讨肝尾状叶静脉分别在正常人群和Budd—Chiari患者中的显示以及测量显示的直径，并评价肝尾状叶静脉在Budd—Chiari综合征的诊断价值。方法14例Budd—Chiari综合征MRI资料(Budd—Chiari组)和54例上腹部MRI增强检查阴性病例(正常组)，在横断位上观察正常组和Budd—Chiari组肝尾状叶静脉的显示，分别计算其显示率，测量正常组和Budd．Chiari组显示肝尾状叶

2、静脉直径，在其下腔静脉汇入口处测量，并进行比较。结果在MRI横断位上，两组病例中显示的肝尾状叶静脉都为一支，汇人下腔静脉左前壁或前壁，54例正常组显示4例，显示率为7．4％，显示直径为0．2～0．34em，平均0．26cm；14例Budd—Chiari组显示9例，显示率为64％，显示宽径为0．4—1．69em，平均0．73am。Budd—Chiari组肝尾状叶静脉的显示率及显示直径大于正常组，差别有统计学意义(P<0．05)。结论在综合判断肝脏形态及血供的前提下，肝尾叶静脉显示及扩张且扩张直径I>0．4cm，要高度怀疑Budd—Chiari综合征的可能。【关键词】肝尾
