What are some common uses of the procedure?
Intravascular ultrasound is most often used to visualize the coronary arteries in conjuction with or to help plan for catheter angiography or angioplasty and vascular stenting. Unlike angiography, intravascular ultrasound can show the entire artery wall and reveal more information about plaque build up (atherosclerosis). Information from intravascular ultrasound often affects treatment decisions, such as the sizing of a stent and where it should be placed. It is often used after angioplasty and vascular stenting to confirm the stent has been placed correctly and that the procedure has addressed the problem.
