Figure 2 Case 1 With Acute Coronary Syndrome

The CT characteristics of a culprit lesion in a 40-year-old male patient presenting with acute coronary syndrome. (A) Volume rendering. (B) Curved MPR. (C) Magnified view of the region of interest from (C). (D) Coronary angiogram. The white arrows in (A) and (D) show the site of luminal obstruction or culprit lesion. As shown by the solid yellow arrows at 2 sites in the culprit lesion in (C), the lesion is positively remodeled as compared with the normal coronary segment proximal to the lesion (denoted by interrupted arrows). Remodeling index in this patient was 1.43. An NCP <30 HU represents the probability of a soft plaque (red circles are placed along the course of low attenuation), and 30 HU <NCP <150 HU denotes a fibrous plaque (green squares). CT = computed tomography; LAD = left anterior descending artery; MPR = multiplanar reformation; NCP = noncalcified plaque.
