Computed tomography-based assessment of pericoronary adipose tissue in cardiovascular diseases: Diagnostic and prognostic implications

Figure 1 Pericoronary adipose tissue attenuation measurement in proximal 40 mm segments and lesion-specific regions. A-C: Schematic of pericoronary adipose tissue (PCAT) attenuation measurement in the proximal 40 mm segments of the three coronary arteries (left anterior descending artery, left circumflex artery, right coronary artery); D and E: Schematic of lesion-specific PCAT attenuation measurement at the site of coronary lesions; F: Cross-sectional PCAT measurement. The measurement radial range is defined as the PCAT within a distance equal to the vessel diameter. LAD: Left anterior descending; CX: Circumflex; RCA: Right coronary artery.

Figure 2 Workflow diagram of pericoronary adipose tissue radiomics. LAD: Left anterior descending; CX: Circumflex; RCA: Right coronary artery; CAD: Coronary artery disease; MACE: Major adverse cardiac event; ROC: Receiver operating characteristic; AUC: Area under the curve.
