What is this test?
The CT Calcium Score is a specialized, non-contrast computed tomography (CT) scan designed to measure the amount of calcium buildup within the walls of the coronary arteries — the vessels responsible for supplying blood to the heart muscle. Unlike traditional CT angiography, this test does not require contrast dye and provides a quick and non-invasive way to quantify coronary artery calcification, which is a key marker of atherosclerosis (hardening and narrowing of arteries due to plaque). The amount of calcium detected correlates with the risk of developing coronary artery disease (CAD) and future cardiac events.
What is it used for?

• Assessing the presence and extent of coronary artery calcification as an early indicator of atherosclerosis
• Estimating an individual’s risk of coronary artery disease, heart attacks, and other cardiovascular events
• Guiding preventive treatment strategies such as lifestyle modification, medication, or further cardiac testing
• Helping physicians stratify patients into low, moderate, or high cardiovascular risk categories, especially when traditional risk factors are borderline or uncertain
• Monitoring progression of coronary calcification over time in patients under preventive care

Who should get this test?

• Generally recommended for asymptomatic adults who have intermediate risk for heart disease based on clinical factors like age, family history, cholesterol levels, smoking status, diabetes, or hypertension
• Patients with no symptoms but with known cardiovascular risk factors to better define their heart disease risk profile
• Individuals uncertain about their risk who want a more personalized assessment beyond standard blood tests and clinical evaluations
• Sometimes used before initiating certain therapies or interventions to tailor preventive measures appropriately

Preparation Required:

• No special preparation is needed before the scan — no fasting or medication adjustments
• Since this is a non-contrast scan, there are no risks related to contrast dye

How is the procedure performed?
The patient lies comfortably on the CT table, usually supine. Electrodes may be placed on the chest to synchronize imaging with the heartbeat for clearer pictures. The scan itself takes approximately 5 minutes, during which low-dose X-ray images are captured to detect and measure calcium deposits in the coronary arteries. The process is quick, painless, and does not require intravenous contrast.
Risks & Safety:
The CT Calcium Score scan uses very low-dose radiation, significantly lower than a standard CT angiogram, and does not involve any contrast agents, eliminating risks of allergic reactions or kidney damage. The minimal radiation exposure is justified by the valuable information gained about cardiovascular risk and prevention.
Results:
The scan produces a calcium score, a numerical value that reflects the total amount of calcium detected in the coronary arteries. Scores are interpreted as follows:

• A score of 0 indicates no detectable calcium and very low risk of coronary artery disease.
• Scores between 1-100 suggest mild calcification and low to moderate risk.
• Scores above 100 indicate moderate to severe calcification and higher risk of cardiovascular events, warranting closer clinical management.
  Your healthcare provider will review the results to help tailor a personalized plan for heart health, which may include lifestyle changes, medications, or further testing.

Short Statement:
A quick, non-invasive CT scan that measures calcium deposits in coronary arteries, providing a crucial early indicator of heart disease risk and guiding preventive care.
