CT Coronary angiogram:
A CT coronary angiogram is performed to look at the blood supply to the heart muscle. The coronary arteries arise from the aorta and supply the heart itself with blood.
The CT uses an injection of contrast material and X-ray to examine the arteries that supply your heart.
Usually this is done with an angiogram which is an invasive procedure; however with advances in technology CT scan in some patients can be as informative as an angiogram with none of the risks involved with an invasive angiogram.
What happens on the day:
On the day, the radiographers/radiologists (x-ray doctors) will explain the procedure to you and consent you for the scan. They will also place a small plastic tube into a vein in your arm.
You will then be transferred to the scanning room where you will lie on the couch of the CT scanner. You will then be asked to put your arms behind your head while the radiographer places small stickers called electrodes on your chest to monitor your heart rate.
During the scan, you will be asked to take a breath in and hold for about 10 seconds several times. This will enable the scanner to take clear pictures.
The cannula in your arm will be attached to a pump injector which will automatically deliver the contrast when required. The injection will make you fell warm all over and may give you a funny taste in your mouth. This is quite normal.
Results:
The results will be passed on to your cardiologist whom will be able to discuss them with you at your next appointment.
