摘要 目的 以超声心动图为对照标准,探讨64层螺旋CT采用不同R-R间期间隔重建在评估左心室功能时有无差异.方法 对临床拟诊冠心病的58例患者进行64层螺旋CT扫描,分别以R-R间期的5%与10%为间隔重建图像进行左心室功能分析,并将所得测值与超声心动图结果进行分析.结果 2种方法测得的左心室功能指标相关性r=0.890~0.949,与超声心动图测得的左心室功能指标相关性r=0.906~0.968.2种方法测值相仿,差异无显著性.2种方法测得的左室收缩末期容积(ESV)、舒张末期容积(EDV)与每搏输出量(SV)较超声心动图大,左室射血分数(EF)较超声心动图小,差异有显著性(P<0.01).结论 本研究表明运用64层螺旋CT扫描时,以R-R间期的5%与10%为间隔重建图像在分析左心室功能方面具有较好的相关性,并且10%为间隔的重建方法更节约时间.
