Beyond plaque and stenosis: Coronary inflammation imaging with the fat attenuation index.
Pericoronary adipose tissue (PCAT) imaging has emerged as a promising noninvasive marker of coronary inflammation and an adjunctive risk-stratification tool beyond conventional coronary computed tomography angiography (CCTA) findings such as luminal stenosis and plaque morphology. The fat attenuation index (FAI), deriv...
