calcium scoring
A non-contrast CT technique that quantifies coronary artery calcification as a marker of atherosclerotic burden.
Full Definition
Calcium scoring, also known as coronary artery calcium (CAC) scoring, is a non-contrast CT imaging technique that measures the amount of calcium deposits in coronary arteries. The examination uses the Agatston method to quantify calcium, providing a numerical score that correlates with atherosclerotic plaque burden and cardiovascular risk. Calcium scoring is valuable for risk stratification in asymptomatic patients and can guide decisions regarding preventive therapy. The technique is performed without contrast material, making it suitable for patients with renal impairment or contrast allergies. Results are typically reported as Agatston scores with percentile rankings for age and gender.
Usage
Usage note: Always specify the scoring method (usually Agatston) and include percentile ranking when available.
