WebThe concordant coronary CTA + CTP assessment exhibited the highest diagnostic accuracy values versus ICA (95.8% in the territory-based analysis). The diagnostic accuracy of CTP was significantly higher than that of coronary CTA (75% vs. 30.5%; p < 0.001). The radiation exposure of coronary CTA + CTP was 4.15 ± 1.5 mSv. Conclusions: WebCT fractional flow reserve (FFR CT) is a physiologic simulation technique that models coronary flow from routine coronary CT angiography (CTA). To evaluate lesion-specific ischemia, FFR CT is measured 2 cm distal to a stenotic lesion. FFR CT greater than 0.8 is normal, 0.76-0.8 is borderline, and 0.75 or less is abnormal. on my way song jlo
