From: High risk plaque criteria by multislice coronary CT angiography in patients with stable vs. unstable coronary artery disease: analytic cross-sectional study

Fig. 2

Plaque characterization by CCTA; positive remodeling index was obtained from the ratio of lesion plaque area (a) and reference lumen area at d; in the case represented RI = 21.5 mm2/15.8 mm2 = 1.36. Plaque burden was obtained by the ratio of lesion plaque area (a) minus lesion lumen area at b; in the case represented PB = (21.5 mm2 – 1.3 mm2)/21.5 mm2 = 0.93.9. In c, napkin ring lesion is illustrated with inner hypodense core and hyper dense outer rim. In e, ROI was applied on NR lesion and revealed inner LAP (38.3 HU ± 18.7) and outer hyperattenuating rim (127.2 HU ± 15.3). In f, stable calcified lesion (non-high-risk atherosclerotic plaque) is illustrated
