CT Coronary Calcium Score

What is a Coronary Calcium Score Scan?

Commonly known as a Calcium Score, this test determines the amount of accumulated (calcified) plaque in the walls of the coronary arteries. Calcium in artery walls is an indicator of the development of Ischaemic Heart Disease (IHD). Calcium build up in artery walls can contribute to artery narrowing that restricts blood flow to the heart. Symptoms of which may include chest pain, discomfort or shortness of breath. In the early stages of plaque accumulation, patients may however have no symptoms. The Calcium Score can therefore help determine the future risk of coronary events occurring in symptomatic and asymptomatic patients. Imaging Central conducts fast, low-radiation-dose Calcium Scores on its state of the art CT scanners in Claremont.
