Representative CCTA image of PCAT around LAD. A hemodynamically significant stenosis (FFR = 0.73) in the middle segment of LAD. PCAT CT attenuation was defined as the mean CT attenuated value within a radial distance equal to the diameter of the vessel. The length of the lesion-based PCAT was defined from the proximal to the distal shoulder of the lesion (A), the vessel-based PCAT was focused on the proximal 40-mm segments of all three major epicardial coronary vessels (10 to 50 mm from right coronary artery ostium) (B). LAD, left anterior descending artery; PCAT, pericoronary adipose tissue.
