This test uses X-rays to create detailed images of the blood vessels in the abdomen and pelvis.



CT angiography (CTA) uses X-rays to create detailed images of the blood vessels in the abdomen and pelvis. It is done to find blood clots, blockages and other problems with blood vessels in the abdomen or pelvis.

  • CTA is done before and after a dye is injected into a vein in the arm or hand.
  • The dye helps to highlight the blood vessels in the abdomen and pelvis, so they can be seen better.

Here are some things you should know before having CT angiography (CTA):

  • You may be told not to eat or drink for at least four hours before the test.
  • The test is painless, but you must lie still during the exam. Moving can blur the images.
  • Generally, a complete scan takes only a few minutes. New scanners work even faster.
  • You will be given a contrast dye to help the blood vessels in your abdomen and pelvis show up better in the pictures.
  • The contrast dye may cause you to feel flushed or to have a bad taste in your mouth for a short time.

The costs for this test include the charge for the test (facility charge) and physician charges (for performing or interpreting the test). You may get separate bills from the facility and the physician's office.

What should I ask my health care provider before having this test?

  • Can I eat before the test? If not, how many hours before the test should I stop eating?
  • Do I need to have the test with dye? If I do, should I be concerned if I have allergies?
  • Is there any special preparation for the test? (If so, get clear steps to follow.)
  • What is the reason for the test? Are the test results likely to change my treatment plan? If not, why do I need the test?
  • Are there any less expensive, but effective, alternatives to my getting this test?
