Distribution of hybrid PET-CT findings. Flowchart demonstrating the distribution of the hybrid PET-CT findings and revascularization performance among the three imaging parameters, i.e. PET perfusion abnormalities, CCTA-derived obstructive CAD, and CCTA-derived HRP. CAD, coronary artery disease; CCTA, coronary computed tomography angiography; CT, computed tomography; HRP, high-risk plaque; PET, positron emission tomography.
