Research Notes on CT Angiography


CT angiography uses x-rays to visualize blood flow in arterial and venous vessels. A contrast dye is injected through a vein in the arm. A machine then takes x-rays from different views. This test may be performed on vessels throughout the body. CT Angiography is useful in detecting many problems that include atherosclerosis, aneurysm or embolism.1

Fast Facts:

  • Pregnant women should not have this test due to the use of x-ray.2
  • The test typically takes 10 to 25 minutes.2
