A computed tomography (CT) coronary angiogram is a minimally invasive imaging test. It allows your doctor to look at the arteries that carry blood to the heart in order to diagnose and treat a number of heart conditions.
St. Joseph's Heart & Vascular Institute provides exceptional diagnostics for our heart and vascular patients. Our physicians use the latest technology to ensure an accurate diagnosis so we can provide you with the best course of treatment available.
Unlike a traditional coronary angiogram, CT coronary angiogram does not involve your doctor inserting a catheter into the body. Instead, this procedure uses special X-ray equipment to take pictures and a computer that uses them to create 3-D views.
The test may take 10 minutes to 2 hours, depending on whether contrast (a liquid that improves the image) is used.
Before the scan:
During the procedure, you will lie on a table that slides into the CT scanner, a large machine with a hole in the middle. The technologist will ask you to hold your breath for a few seconds during your scan.
After the test, you can go back to your normal diet and activities right away. Any contrast will pass naturally through your body within a day.
After the procedure, you may need to wait briefly while your images are being reviewed. Your doctor will discuss the test results with you during a follow-up appointment or over the phone.
If you are scheduled for a CT angiogram, be sure to follow any instructions your doctor provides. Also:
