A CT Angiogram (CTA) uses a combination of x-rays and computer technology to make detailed 3-D images of blood vessels in the head and neck. The images can show weakened sections of vessels and visualize blood flow. This procedure is non-invasive and is safer than a Catheter Angiogram.
Your doctor may order this test if there are suspected aneurysms, stroke or plaque build-up. The test can also be used to guide surgery, evaluate arteries feeding a tumor, or to find obstructions in blood vessels.
How to Prepare:
- Notify the technician of any allergies and if you might be pregnant
What to Expect:
- Before the procedure, you will receive an IV containing a contrast dye
- You will lie on a table that will move through the scanner
- After contrast dye is injected through your IV, the CT machine will take fast pictures of your head and neck
- The test usually takes less than 10 minutes to complete
After the Test:
- Drink plenty of water to flush out the contrast dye
- You can resume a normal diet
- The radiologist will send a report to your doctor
