What is a coronary angiogram?

Coronary angiograms are x-rays used to assess narrowing or blockages in your coronary arteries. A thin tube called a catheter is threaded through an artery up toward your heart, and an x-ray contrast solution is injected through the catheter and into the coronary arteries. X-rays then capture images of blood flow through the arteries. Angiograms can also be used to measure blockage in:
  • Carotid arteries, leading to the brain
  • Renal arteries, leading to the kidneys
  • Peripheral arteries, leading to the arms or legs
