Figure 2 Intravascular ultrasound (IVUS) image (A) and elastogram (B) with corresponding histology of a coronary artery with a vulnerable plaque. The IVUS image reveals an eccentric plaque between the 6- and 12-o’clock positions. The elastogram shows high-strain regions (yellow) at the shoulders of the plaque surrounded by low-strain values (blue). The histology reveals a plaque with a typical vulnerable appearance: A thin cap with a lack of collagen at the shoulders (C) and a large atheroma with heavy infiltration of macrophages (D).
