Coronary CT Calcium Scan, in Visit Clinic

A CT coronary calcium scan can be worthwhile for asymptomatic adults at intermediate cardiovascular risk: it refines risk assessment, helps decide on statin therapy, and motivates lifestyle changes. It’s quick, low‑radiation, and not useful for low‑risk people (or when treatment is already indicated) and doesn’t detect non‑calcified plaque or replace angiography for symptoms. Discuss benefits and limits with your clinician.

A coronary calcium CT scan is a non‑invasive, low‑radiation CT test that detects and measures calcified plaque in the coronary arteries. It produces a calcium (Agatston) score estimating a person’s coronary atherosclerosis and future heart‑attack risk. It’s used for cardiovascular risk stratification—especially when risk is uncertain—and helps guide preventive strategies; it doesn’t reliably show non‑calcified plaque or exact artery narrowing.

A high coronary CT calcium score indicates a large burden of calcified atherosclerotic plaque and is associated with higher risk of obstructive coronary artery disease and future heart attack. However, it does not directly measure vessel narrowing or acute clot; non-calcified plaques can be missed. Further evaluation (for example, functional testing or CT angiography) is often needed to assess actual blockages and guide treatment.

A CT coronary calcium (CAC) score typically costs about $50–$400 in the United States, £100–£350 privately in the UK (the NHS may fund it if clinically indicated), and roughly ₹1,000–₹6,000 in India. Prices vary by facility, the imaging package (reporting, heart-rate control, contrast) and insurance; check local providers for exact fees and coverage.

Yes—coronary CT angiography (CTCA) can detect coronary artery blockages by visualizing calcified and non‑calcified plaque and estimating stenosis. A noncontrast coronary calcium CT measures calcified plaque burden but won’t show soft plaque or exact narrowing. CTCA is noninvasive with a high negative predictive value for ruling out significant disease; invasive coronary angiography remains the gold standard for diagnosis and treatment.

Costs vary by country and provider. In the United States a CT calcium (CAC) score commonly ranges from $50 to $400 (often $75–$250). In the United Kingdom the NHS rarely offers it routinely; private clinics charge about £100–£250. In India costs are roughly ₹1,500–₹6,000. Final price depends on location, facility, and whether reporting or cardiology consultation are included.
