A CT coronary angiogram is used to directly visualise the heart arteries and the fatty deposits (plaques) that can develop within them
This fatty plaques can mean your heart is not getting the blood supply it needs, which can cause chest pain (angina) and heart attacks
involves injecting an iodine based dye into your bloodstream to highlight your blood vessels
You may also be given some medication to slow down your heartbeat, making it easier to take images
