The individual stent struts can be recognized as signal rich, bright yellow structures casting a dorsal shadow on the vessel wall. Stent struts in 5 o'clock position are not apposed against the vessel wall (arrows). There is tissue protruding between the stent struts in 11 o'clock position, and mural thrombus formation in 2 and 4 o'clock position visible (open arrows).
