What: CT angiography is used to examine blood vessels.

Physicians may use the procedure to:

  • Identify disease and aneurysms in the aorta or in other major blood vessels.
  • Guide surgeons making repairs to diseased blood vessels, such as implanting or evaluating a stent.
  • Identify dissection in the aorta or its major branches.
  • Screen individuals for arterial disease, especially patients with a family history of arterial disease or disorders.
  • Detect thrombosis (clots) in veins.

The images captured in this scan allow the radiologist to construct a three-dimensional image of your heart and measure blood flow, as well as narrowing of the arteries.

This study will require IV injected contrast agents to help us visualize certain tissue or blood vessels. Some patients describe a metallic taste or tingling sensation right after the injection. This is normal and usually subsides very quickly.
