Figure 3. OCT imaging of the BRS vs. Drug-eluting stents. (A) OCT image of BRS. The struts are translucent, which leads to excellent imaging of the artery; (B) OCT images of metallic stent. The metallic struts are not translucent to the OCT and that led to the typical shadow into the vessel wall with “sunflower artifact”. OCT: Optical coherence tomography; BRS: bioresorbable scaffold.
