(B) Expanded view of dotted region in A, demonstrating a large calcific nodule (blue arrowheads) and a lipid pool with a thin fibrous cap (black arrow). (C) Expanded view of an OFDI cross-sectional image obtained at location of the black arrow in B and red arrowhead in Figure 1C, shows a lipid pool with a thin fibrous cap (black arrow) and a dense band of macrophages at the cap–lipid pool interface (green arrow). A thin flap of tissue (black arrowhead) can be seen over the cap. Scale bar in A, 5.0 mm. Scale bar in B, 1.0 mm. Tick marks in C, 0.25 mm. L = lipid pool.
