Coronary computed tomography angiography adipose tissue attenuation in diabetic patients with myocardial ischemia and non-obstructive coronary arteries

Figure 2 Receiver operating characteristic curves for identifying ischemia with non-obstructive coronary arteries in patients with type 2 diabetes mellitus. A: Clinical variables vs left anterior descending artery-pericoronary adipose tissue attenuation and their combination; B: Clinical variables vs left circumflex-pericoronary adipose tissue attenuation and their combination; C: Clinical variables vs right coronary artery-pericoronary adipose tissue attenuation and their combination. The diagnostic performance was assessed by comparing the area under the curve for each parameter. Combined models demonstrated improved diagnostic accuracy compared with individual indicators. LAD: Left anterior descending artery; PCATa: Pericoronary adipose tissue attenuation; LCX: Left circumflex; RCA: Right coronary artery.
