What is CT coronary angiography?
Computed tomography (CT) coronary angiography is a type of x-ray imaging procedure that uses a contrast dye, a CT scanner and a computer to produce images of the heart and the blood vessels that supply it (coronary arteries).
This test helps determine narrowing and blockages of coronary arteries. It uses an iodine-based contrast dye to ‘light up’ the heart and its blood vessels and clearly define their appearance on the CT images. (Read more: Coronary heart disease)
Coronary arteries may become narrow and blocked due to the build-up of plaque (fat, cholesterol and calcium deposit) along their inner lining.
