Calcium Score
CT Calcium Scoring
A calcium score is a specialised CT scan that measures the amount of calcium buildup in the coronary arteries, which supply blood to the heart. The presence of calcium can indicate plaque formation and early signs of coronary artery disease. This quick, non-invasive test helps assess a person's risk of heart attack or other cardiac events and supports doctors in making informed decisions about prevention, monitoring, and treatment.
