摘要 目的了解临床上持续静脉滴注法心肌声学造影(MCE)定量心肌血流判断存活心肌的可行性与可靠性。方法对19例前壁心肌梗塞患者行持续静脉滴注法MCE,设置不同触发间隔,采集图像后脱机分析及彩色编码。MCE检查后两天内完成正电子断层显像(PET)。计算灌注正常区域和灌注缺损区域的A·β值,根据A·β值确定心肌存活与否,将判定结果PET进行对照。结果16例病人(84%)获得满意图像,灌注正常区和灌注缺损区的A·β值分别为62.41±12.97、3.61±1.69,灌注缺损区标化后的A·β值都小于0.23,与动物试验所得结果相似,PET判定坏死的心肌节段,MCE示相应区域的A·β值显著减少,彩色编码示同一区域灌注缺损。结论MCE能用于临床上从血流定量水平判断存活心肌。
