Figure 4 Echolucent coronary plaque imaged in vivo by optical coherence tomography (OCT) (A) and intravascular ultrasound (IVUS) (B). (A) An atherosclerotic plaque extending from 5 o’clock to 12 o’clock contains regions consistent with fibrous tissue (f) and a homogeneous, signal-poor region (arrow), which is partially obscured by a guidewire shadow artifact (*). The minimum cap (arrowhead) thickness measured 122 ± 7 µm by OCT. (B) The corresponding IVUS image shows the same echolucent region (arrow). Tick marks, 1 mm.
