What It Is

CT angiography makes use of the latest CT technology and involves taking images of the body. Combining thin section reconstruction with fast scanning, CT angiography can provide exceptional detail of organs and blood vessels. Some of the conditions that doctors use CT angiography to diagnose include coronary artery disease, renal artery stenosis, and thoracic aorta aneurysm.

What to Expect

During the procedure, you will be given an I.V. line, and contrast dye will be injected. This step will take about 10 to 30 seconds and may cause you to experience a funny taste in your mouth or a warm sensation. As the CT scan is performed, you will need to hold your breath for a short time.

How to Prepare

To get ready for your CT angiogram, you should not eat within 3 hours of your appointment at the imaging center. However, you should drink plenty of fluids, ideally water, while avoiding caffeinated beverages. Also, wear clothing that is comfortable and will allow easy access for the I.V. line. Before the scan, inform the nurse or radiologist of any allergies that you know of and do not hesitate to ask questions or express any concerns that you may have about the CT angiogram.

After Your Scan

Following your CT angiogram, you can resume your normal activities, eat normally, and should continue to drink plenty of fluids over the next 24 hours. If you experience any issues or have questions, then contact your physician or radiologist.

Interpreting the Results

A CT angiogram may include as many as thousands of axial slices, which are thin, individual CT scans. In combination with 3D imaging tools and other methods of analysis, these images are reviewed. After the information is analyzed, your referring physician should receive a report of any significant findings about a day after your scan.
