What is a Cardiac CT?


A cardiac CT or CT coronary angiogram assesses the coronary arteries for disease which can result in a heart attack.

What happens during my Cardiac CT ?

A liquid contrast agent, sometimes called contrast medium, is injected into a vein (usually in the arm). Contrast agents allow the coronary arteries to be assessed on CT coronary angiogram images.

Medication to slow down the heart rate might also be given to make the images even clearer and easier to interpret. This will either be given in tablet form or into a vein through a cannula (a thin plastic tube) inserted in the arm.

How long will it take?

This scan will take 10-15 minutes but you will need to arrive an hour beforehand. Following your scan, you will be observed for 15 minutes. Please allow two hours for the entire process.
