A CT calcium score is a specialised CT scan that measures the amount of calcified plaque in your coronary arteries. It is one of the strongest predictors of future cardiovascular events.
A low-radiation CT scan measuring calcium in the coronary arteries to estimate heart attack risk. Ideal for risk refinement and tailored prevention plans.
The CT calcium score service is designed to assess the presence of coronary artery disease by measuring the amount of calcium in the coronary arteries. During the face-to-face consultation, the patient will undergo a non-invasive CT scan. This procedure involves lying on a table that slides into the CT scanner, which takes detailed images of the heart.
Patients can expect to receive a brief explanation of the process, which is quick and typically painless. The results will indicate the level of calcium deposits, helping to evaluate the risk of heart disease. This information is crucial for cardiologists to diagnose potential issues and recommend appropriate lifestyle changes or treatments to improve heart health.
A CT calcium score is a quick, low-radiation CT scan that measures the amount of calcium in your coronary arteries. The resulting score helps estimate your risk of coronary artery disease and future heart events.
The scan itself takes only a few minutes. The full appointment, including preparation and ECG lead placement, is around 30 minutes.
No. Unlike a CT coronary angiogram, a calcium score scan does not require any contrast dye injection, making it even simpler and safer.
No NHS referral is required. You can book directly with us for a private CT calcium score scan.
A score of zero suggests very low risk of coronary artery disease. Scores above zero indicate some calcium is present, with higher scores reflecting greater plaque burden. Your cardiologist will explain your result in context of your overall risk profile and recommend any lifestyle changes or treatments.
