2、SWE检测肝弹性模量。以肝组织病理学结果为金标准,比较SWE、常规超声与肝纤维化病理分期的相关系数、诊断肝纤维化各分期的ROC曲线下面积,以及不同操作者之间的组内相关系数(ICC)。结果SiwE与肝纤维化病理分期的相关系数(r=0.799,95C10.413—0.670,P=0.000)高于常规超声(rI0.530,95C10.721—0.857,P=0.000)。常规超声和SWE诊断肝纤维化病理分期S≥2、S≥3和S4的ROC曲线下面积分别为0.765和0.892、0.763和0.941、0.800和0.9
3、65,SWE高于常规超声(P0.008、P<0.001、P=0.005)。SWE的ICC(0.968,95C10.928—0.986)高于常规超声(0.886,95C10.834—0.921)。结论SWE简便易行,可重复性好,诊断肝纤维化准确性高,能弥补常规超声的不足。【关键词】超声检查;肝炎,乙型,慢性;肝硬化;弹性成像Comparativestudyofreal-timeshearwaveelastographyandultrasonographyintheassessmentofliverfibrosi
