Perivascular fat attenuation index improves the identification of functional myocardial ischemia beyond traditional risk factors: a coronary CT angiography-derived fractional flow reserve study
Perivascular fat attenuation index (FAI) derived from coronary computed tomography angiography (CCTA) is a novel imaging biomarker of coronary inflammation. However, its incremental value in predicting functional myocardial ischemia, defined by CT-derived fractional flow reserve (CT-FFR), beyond traditional cardiov...
