2、高增强(14/21,66.7%),门脉期(19/21,90.5%)及延迟期多消退为低增强(21/21,100%);显示病灶增强均匀8个(8/21),不均匀13个(13/21)。(2)21例肝门部胆管癌病灶增强MRI动脉期多显示为高增强(14/21,66.7%),门脉期以等增强为主(11/21,52.4%),延迟期多显示为等增强(6/21,28.6%)或高增强(12/21,57.1%);显示病灶增强均匀6个(6/21),不均匀15个(15/21)。(3)肝门部胆管癌超声2造影动脉期显示不同增强水平的病灶数与增强MRI比较差异无统计学意
3、义(χ=1.167,P>0.05);2超声造影门脉期及延迟期与增强MRI增强水平显示的病灶数比较差异有统计学意义(χ=24.867、31.500,P<0.05)。肝门部胆管癌病灶超声造影与增强MRI显示增强均匀性的病灶数比较差异无统2计学意义(χ=0.429,P>0.05)。结论肝门部胆管癌在超声造影及增强MRI动脉期表现无明显差异,而门脉期及延迟期的表现则不同,超声造影可作为增强MRI诊断肝门部胆管癌的有益补充,从而增加诊断医师对肝门部胆管癌的诊断信心。【关键词】超声检查;造影剂;磁共振成像;肝门部胆管癌Comparisonbet
