This scan produces multiple images of the vessels and joins them together in cross-sectional views. The 3D images can be manipulated by radiologists and cardiologists to provide clearer views and a more accurate diagnosis. It is a a non-invasive heart imaging test that determines if any fatty or calcium deposits (plaques) have built up in your coronary arteries. It also shows the structure of your heart and any abnormalities you may have had since birth. Over time, plaque can narrow your arteries or even close off blood flow to your heart, causing chest pain or a heart attack. A cardiac CTA may help decide which measures can be taken to avoid these events. For you, it means a faster, less invasive procedure to detect cardiovascular problems.

How do I prepare?

Before the test:
Prescription Medicines

• If you take Cialis, stop taking this medication five days before the test.
• If you take Viagra or Levitra, stop taking this medication 48 hours before the test.
• If you are on Glucophage or a derivative, do not take it the day before the procedure and for 48 hours after the injection. You will have a BUN/Creatinine blood test drawn 48 hours after the procedure. Based on the results, your physician will contact you with further instructions.
• You may be given a prescription for beta blockers to stabilize your heart rate during the procedure.
• Take all other medications unless otherwise instructed by your physician.

Food, Drink, and Tobacco

• Increase your fluid consumption the day before and the morning of your scheduled CTA procedure.
• For 16 hours prior to the exam, you may not have any caffeine (in any form) including coffee, tea, carbonated drinks, or chocolate.
• For 16 hours prior to the exam, do not smoke.
• For 4 hours prior to the exam, do not eat any solid food.

During the study:

• Your heart rate will be monitored by an EKG monitor.
• You will be given a contrast dye through an IV.
• You may be given an IV medication to lower your heart rate.
• During the CT, you will lie on your back. The CT table slides through the opening of the scanner. The table will move forward slightly so that you will be in the proper position for accurate imaging. This process continues until the region of the heart has been thoroughly scanned. You will be asked to hold your breath for periods of 15-20 seconds.

After the study:

• You will be kept for one hour after the procedure for monitoring.
• Be sure to drink plenty of fluids.

How do I find out the results?
A final report will be given to your referring doctor who will talk to you about the results.
