摘要:
目的:探讨Flash双源CT（DSCT）冠状动脉成像(DSCTA)联合双能量心肌灌注显像(DS-CTP)一站式检查对冠心病的诊断价值。方法:对60例临床考虑冠心病的患者行DSCT检查,所有患者均接受冠状动脉造影检查。以冠状动脉造影为标准诊断法,根据冠脉造影结果分为狭窄<50%（阴性）和狭窄≥50%（阳性，诊断冠心病）,计算DSCTA联合DS-CTP（平行试验）诊断冠心病的灵敏度、特异度和准确度。结果:DS-CTA诊断冠心病的灵敏度、特异度和准确度分别为84%、93%和89%;DSCTA联合DSCTP（平行试验）诊断冠心病的灵敏度、特异度和准确度分别为94%、91%和92%，与单独DS-CTA比较，灵敏度和准确度稍有提高，而特异度稍有下降，但都没有达到显著水平。结论:DS-CTA联合DSCTP对冠心病诊断具有很高的诊断价值。但DS-CTA与DS-CTA联合DS-CTP诊断价值无显著差异。
Abstract:
AIM:To evaluate the feasibility of diagnosing coronary stenosis and myocardial ischemia with a single dualenergy CT (DSCT) acquisition method. METHODS: Sixty patients underwent dualsource dual energy CT and conventional coronary angiography (CAG). CAG results served as the “gold standard” to evaluate the diagnosis of coronary artery disease (CAD) and stenosis ≥50% (positive). We assessed the sensitivity, specificity and concordance rate of DSCTA plus DSCTP (parallel trial) in diagnosis of CAD. RESULTS: Sensitivity of DSCTA was 84%, specificity was 93%, and concordance rate was 89%. Combination of DSCTA and DSCTP (parallel trial) resulted in a sensitivity of 94%, specificity of 91%, and concordance of 92%. Compared with DSCTA, sensitivity and concordance is slightly improved, whereas there was a slight decrease in specificity but without reaching significance. CONCLUSION: DSCTA plus DSCTP provide a high diagnosis for CAD. DSCTA plus DSCTP with DSCTA shows no significant difference in the diagnostic value.
