Coronary Artery Calcium Score (CAC)

Non-contrast CT to quantify coronary artery calcification (Agatston score) and stratify cardiovascular risk. No contrast agent required. Ideal for intermediate-risk patients and asymptomatic adults with cardiovascular risk factors. No referral needed.

Coronary artery calcium (CAC) scoring at Radiologie Raboisen 38 uses a non-contrast, ECG-gated CT scan to measure the total calcified atherosclerotic plaque burden in the coronary arteries, producing a standardised Agatston score. This score is one of the most powerful independent predictors of future cardiovascular events available to clinicians, because it measures disease that has actually formed — not merely risk factors that predict it might form. The examination is fast, non-invasive, and does not require intravenous contrast, meaning preparation is minimal: patients eat and drink normally before the scan. ECG gating synchronises image acquisition with the cardiac cycle to produce motion-free images of the coronary arteries. The Agatston score is calculated for each coronary territory (left main, left anterior descending, left circumflex, and right coronary artery) and as a total score. A score of zero — common in asymptomatic middle-aged adults — indicates the absence of calcified atherosclerosis and confers a very low 10-year event risk, often enabling deferral of pharmacological prevention in patients with borderline risk factor profiles. Scores above 100 or above the age-sex-race 75th percentile indicate a need for more intensive preventive treatment. European Society of Cardiology guidelines support CAC scoring as an optional discriminating test for intermediate-risk patients where the decision to initiate statin therapy is genuinely uncertain. At Radiologie Raboisen 38, CAC scoring is offered as part of the practice's cardiology-focused Cardio-CT programme alongside the multi-slice scanner. Dr. Christian Lund, who joined the practice in 2011, holds particular expertise in cardiac imaging including lung CT and heart diagnostics. Results are discussed in a post-scan physician consultation; the written report includes the total Agatston score, per-vessel breakdown, percentile ranking by age and sex, and clinical interpretation. Patients and referring physicians receive images via the online portal.
