摘要
目的探讨心脏双能量CT冠状动脉造影(DE-CTA)结合CT心肌灌注(DE-CTP)对冠心病诊断的准确性。方法对31例临床可疑或已知冠心病的患者行心脏双能量CT和负荷-静息SPECT检查,所有患者在1个月内接受导管造影检查。重建冠状动脉DE-CTA和DE-CTP图像用于冠状动脉狭窄程度和心肌灌注缺损的评判,并以冠状动脉造影为参考标准,建立DECT对冠状动脉狭窄诊断价值的基线值,进而计算DE-CTA加DE-CTP对冠心病诊断的敏感性、特异性、阳性预测值、阴性预测值和准确性。结果 28例患者获得满意的图像质量,以冠状动脉造影为参考标准:(1)DE-CTA显示112支冠状动脉,其中41支冠状动脉狭窄≥50%,诊断冠状动脉狭窄的敏感性、特异性、阳性预测值、阴性预测值分别为81%(38/47)、95%(62/65)、93%(38/41)、87%(62/71),准确性为89%(100/112);(2)DE-CTP显示46支狭窄冠状动脉供血区域心肌灌注缺损,诊断狭窄≥50%冠状动脉的敏感性、特异性、阳性预测值、阴性预测值分别为76%(36/47)、85%(55/65)、78%(36/46)、83%(55/66),准确性为81%(91/112);(4)DE-CTA加DE-CTP诊断52支冠状动脉狭窄≥50%,诊断冠状动脉狭窄的敏感性、特异性、阳性预测值、阴性预测值分别为96%(45/47)、89%(58/65)、86%(45/52)、97%(58/60),准确性为92%(103/112)。结论 DE-CT一次扫描即能获得冠状动脉解剖学和血流灌注信息,可以对冠心病做出综合性诊断。DE-CTP能够为CTA提供有益的补充。
