A representative case of nonobstructive coronary artery disease with negative CT-FFR and a low global ΔCT-FFR. CT-FFR coronary computed tomography angiography−derived fractional flow reserve, ΔCT-FFR CT-FFR lesional gradient, LAD left anterior descending artery, LCX left circumflex artery, RCA right coronary artery. A 55-year-old man with a history of diabetes mellitus underwent a CCTA examination for suspected CAD. CCTA showed 40% stenosis (orange arrow) in the proximal LAD and no significant stenosis in the RCA and LCX. The CT-FFR value was 0.90, 0.84, and 0.92 for the RCA, LAD, and LCX systems, respectively. ΔCT-FFR was 0.10 for LAD and 0 for RCA and LCX because no ischemic plaque was found. Thus, the global ΔCT-FFR was calculated as the sum of the ΔCT-FFR of 0.10
