Cardiac calcium scoring (also called coronary artery calcium scoring, CAC scoring, or heart scan) is a specialized CT scan that measures calcified plaque buildup in your coronary arteries, the blood vessels that supply oxygen to your heart muscle. This quick, non-invasive screening detects atherosclerosis (hardening of the arteries) before symptoms appear, helping predict your risk of heart attack and coronary artery disease.
How cardiac calcium scoring works:
• Uses low-dose CT imaging to detect calcium deposits in coronary arteries
• Calculates an Agatston score ranging from 0 (no detectable plaque) to over 1,000 (extensive disease)
• Provides age-, sex-, and race-specific percentile ranking
• Takes just 10-15 minutes with no contrast dye or IV needed
Unlike traditional risk assessments that rely solely on factors like cholesterol and blood pressure, cardiac scoring provides direct visualization of plaque in your arteries, offering a more accurate picture of your actual heart disease risk.
Cardiac calcium scoring is ideal for:
• Early detection of coronary artery disease in asymptomatic patients
• Risk assessment for people with borderline or intermediate cardiovascular risk (10-year risk 5-20%)
• Guiding decisions about statin therapy and lifestyle interventions
• Predicting long-term cardiovascular events with greater accuracy than traditional risk factors alone
Your doctor may order cardiac calcium scoring when traditional risk assessment tools do not provide a clear picture of your cardiovascular risk. This commonly occurs in patients with intermediate risk who fall into a gray zone where the benefits of statin therapy or aspirin are uncertain.
Common reasons your doctor ordered this test:
Unclear cardiovascular risk:
• Borderline high cholesterol and uncertainty about taking statins
• Multiple risk factors but unclear overall risk
• Conflicting risk assessments from different calculators
• Younger patients (40–55) with a strong family history of premature heart disease
Treatment decision guidance:
• You stopped taking statins due to side effects and want to reassess disease burden
• Your doctor wants objective evidence to guide treatment intensity
• You are symptom-free but have concerning risk factors
Risk stratification needs:
• Metabolic syndrome or multiple cardiac risk factors
• Chronic inflammatory conditions such as rheumatoid arthritis or lupus
• Family history of premature heart disease
Yes, you need a referral (also called a doctor’s order or prescription) to get a cardiac calcium scoring scan at American Health Imaging.
What your referral does:
• Confirms that cardiac calcium scoring is medically appropriate for your age and risk factors
• Is required for scheduling your appointment
• Helps ensure the scan is used for appropriate clinical indications
• Allows your doctor to receive and interpret your results
Once your doctor sends the order to American Health Imaging, we’ll contact you to schedule your appointment and explain the $199 self-pay cost.

American Health Imaging offers cardiac calcium scoring at select locations across Alabama, Georgia, Texas, Florida, and South Carolina.
Because cardiac calcium scoring requires specialized CT equipment and trained cardiovascular imaging radiologists, not all locations offer this service. We recommend calling ahead to confirm availability at your nearest center.

Cardiac calcium scoring detects and quantifies coronary artery calcification, a marker of atherosclerotic plaque buildup in the arteries supplying your heart muscle. This is the underlying disease process responsible for most heart attacks.
Risk categories:
• Score 0: Very low risk
• Score 1–10: Low risk
• Score 11–100: Mild disease
• Score 101–300: Moderate disease
• Score greater than 400: Extensive disease
Calcium scoring predicts future heart attack risk and overall cardiovascular disease burden but does not detect soft plaque or active blockages.
Preparing for a cardiac calcium scoring scan requires minimal advance preparation.
Before your appointment:
• No fasting required — eat and drink normally
• Continue all regular medications unless advised otherwise
Day of your appointment:
• Avoid caffeine for 4 hours before the scan
• Avoid smoking for 4 hours before the scan
• Wear comfortable clothing without metal fasteners
• Remove jewelry and metal objects
• Arrive 15 minutes early for paperwork
No IV, contrast dye, exercise, or recovery time is required.
Your cardiac calcium scoring scan is a quick, painless procedure that takes just 10–15 minutes total.
What to expect:
• Simple positioning on the CT scanner
• Brief breath-hold instructions
• No injections or contrast dye
• No physical exertion
Most patients are pleasantly surprised by how fast and easy the exam is compared to stress tests or other heart imaging.
After your cardiac calcium scoring scan is complete, you can leave immediately and resume all normal activities.
Immediately after your scan:
• Drive yourself home
• Resume eating, working, and exercising
• No activity restrictions or recovery time
Your images will be reviewed by board-certified cardiovascular radiologists, and results will be sent to your referring doctor.
Your doctor typically receives the results within a few hours after the report is finalized.
You will receive:
• A text message with a link to your Scanslated® patient-friendly report
• Easy-to-understand explanations of your calcium score
• Information to help guide your next steps
Most patients receive their report within 48 hours.
The actual scan takes just 10–15 seconds of breath-holding.
Total appointment time:
• Approximately 10–15 minutes from check-in to finish
This makes cardiac calcium scoring one of the fastest and most convenient cardiovascular screening tests available.
Most insurance plans, including Medicare, do not currently cover cardiac calcium scoring because it is considered a preventive screening test.
Payment options at American Health Imaging:
• Self-pay price: $199
• HSA and FSA funds accepted
• CareCredit® payment plans available
Many patients find this affordable investment worthwhile for understanding their true heart disease risk.
The Agatston score is the standard measurement used to quantify coronary artery calcium.
Score ranges:
• 0: No detectable calcium, very low risk
• 1–10: Minimal plaque
• 11–100: Mild plaque
• 101–300: Moderate plaque burden
• 301–400: Moderately high risk
• Greater than 400: Extensive plaque, high cardiovascular risk
Higher scores indicate a greater likelihood of future cardiovascular events and may require more aggressive preventive treatment.
Cardiac calcium scoring is best for asymptomatic adults ages 40–75 with intermediate cardiovascular risk and uncertainty about preventive treatment decisions.
Ideal candidates include:
• Patients with borderline or intermediate 10-year risk (5–20%)
• Family history of premature heart disease
• Multiple cardiovascular risk factors
• Patients uncertain about starting statin therapy
It is not recommended for low-risk individuals or patients with known coronary artery disease.
Yes. Cardiac calcium scoring is generally safe for patients with pacemakers or implantable cardioverter-defibrillators (ICDs). CT scanning does not use magnetic fields and does not interfere with these devices.
Cardiac calcium scoring measures calcified plaque to assess cardiovascular risk in asymptomatic patients and does not require contrast dye.
Coronary CT angiography (CTA):
• Uses IV contrast
• Visualizes coronary arteries directly
• Detects blockages and narrowing
• Has higher radiation exposure
Calcium scoring is best for preventive screening, while CTA is used to evaluate symptoms or known disease.
No. Cardiac calcium scoring specifically detects calcified coronary plaque and does not evaluate:
• Soft (non-calcified) plaque
• Heart valve disease
• Arrhythmias
• Cardiomyopathy
• Heart failure
It is best used as a preventive risk-assessment tool rather than a comprehensive heart disease evaluation.
