Coronary CT Angiography
A Coronary CTA is a heart-imaging test which non-invasively determines whether either fatty deposits or calcium deposits have built up in the coronary arteries.
According to the statistical data from the World Health Organization (WHO), coronary artery disease is one of the top causes of death. It mainly results from degenerative blood vessels or the formation of lipid-containing plaques which gradually block the bloodstream. Heart disease is often found in patients with diabetes, hypertension, hyperlipidemia, as well as those suffering from stress and heavy smokers.
CT technology has been rapidly evolving over the past several years. It now provides a high-resolution and high-contrast image of a small and beating organ such as the heart.
Patients undergoing a Coronary CTA scan receive an iodine-containing contrast dye as an intravenous solution to ensure the best images possible. During the examination, this usually takes about 10 minutes, x-rays pass through the body and are picked up by special detectors in the scanner.
