Figure 3 Molecular and structural targets for imaging. Cross section of a coronary artery containing plaque assumed to be rupture-prone. Potential targets for imaging are highlighted. They comprise: 1) the large lipid-rich necrotic core (orange asterisk), 2) thin fibrous cap (blue arrows), 3) expansive remodeling (green arrow), and 4) vasa vasorum and neovascularization (red open circles).
