CT Angiography

What is CT Angiography?

CT Angiography is a test that uses x-rays to see blood flow through your arteries and veins. Together CT angiography - showing kidneys and aortic arterywith a computer, detailed images and 3D pictures are created.

Why should I have a CT Scan?

This procedure can be used to study the blood flow to your brain, legs, lungs, kidneys, and so on. Your doctor may order this test if you have pain in your legs, high blood pressure, tumors, and if he/she suspects a stroke. This test requires an order from your doctor, nurse practitioner, or physician assistant.

How long will the exam take?

This test takes about 30 minutes to complete.

What do I do before the exam?

You will be instructed not to eat or drink for at least 4 hours before the test. Certain exams require a special dye (also called contrast) in your body before the test starts. This contrast can highlight specific areas that will result in a better x-ray picture. Contrast can be given in a variety of ways: IV (a needle in your arm) or a liquid that you drink. When you are scheduled for the exam, you will be told if you will receive contrast or not.

Most of our contrast contains iodine, so please inform us (or your doctor) if you have an allergy to iodine. Make sure to ask about any prescription medications you might be taking. If you have any questions about the preparation instructions, please call our office at 743-0445.

What will the exam be like?CT scanner

You will be asked to wear clothes with little or no metal on them or you may be asked to change into a hospital gown. You will be escorted to the exam room and placed on the table.

The CT scanner consists of a narrow table and a large donut-shaped ring. For the exam, the table will move through the opening as a series of x-ray beams rotate around you. A computer in the machine will take these pictures and recreate a 3D image. You will need to remain still for the exam because movement can make the pictures blurry.

What happens with my test results?

One of our specially trained radiologists will study the x-ray films from your test and send a typed report to your doctor, nurse practitioner, or physician assistant. They can then discuss the results with you in detail.

What if I have further questions?

If you have any further questions or concerns about this procedure, please contact our office at 743-0445 or call your doctor, nurse practitioner, or physician assistant.
