摘要 目的用激光多普勒对照研究声诺维超声造影评价兔VX2肝癌血流灌注的可靠性.方法团注法声诺维超声造影及激光多普勒分别扫查8只兔VX2肝癌表面及左肝正常肝组织,绘制时间-强度曲线获取峰值强度(PI),激光多普勒计算局部平均血流灌注量,2种方法统计学分析其相关性.结果VX2肝癌表面及其旁肝组织的峰值强度分别为(3.69±1.02)、(2.55±1.13);VX2肝癌表面及正常肝组织的平均血流灌注量分别是(2.93±0.68)、(0.96±0.34),经统计学分析2种方法相关性良好(r=0.97,P<0.01;r=0.94,P<0.01).结论声诺维超声造影评价肝癌和正常肝脏组织血流灌注可靠,具有较广阔的应用前景.
