Abstract
Coronary computed tomography angiography (CCTA) is the most commonly used modality for noninvasive plaque imaging in clinical settings. Characteristics of rupture-prone vulnerable plaques include positive remodeling, low attenuation, and napkin-ring sign in CCTA. About 60% of all vulnerable plaques have these characteristics, and these coronary lesions often result in plaque rupture. Identification of such groupings of coronary artery characteristics has been used to predict cardiovascular events.
