目的评价应用国产化冠状动脉CT血管造影（CTA）图像模拟的无创血流储备分数（FFRCT）对功能性心肌缺血的诊断价值。方法回顾性纳入2012年8月-2015年7月解放军总医院同期行冠脉CTA和FFRCT检查的39例患者,基于冠脉CTA图像通过流体力学原理模拟计算FFRCT值,以有创的FFR值为参考标准,分别从患者水平和血管水平计算FFRCT对功能性心肌缺血的诊断准确性、特异度、敏感度、阳性预测值和阴性预测值。结果在患者水平FFRCT的诊断准确性为82.05%,敏感度为83.33%,特异度为80.95%,阳性预测值为78.95%,阴性预测值为85.00%;在血管水平FFRCT的诊断准确性为76.79%,敏感度为69.57%,特异度为81.82%,阳性预测值为72.73%,阴性预测值为79.41%...
