What is a coronary calcium score?
A coronary calcium score (CAC score) is a quick CT scan of the heart without contrast. It measures the amount of calcium in the walls of the coronary arteries, which is a marker of plaque build-up.
Your doctor uses the score, together with your other risk factors such as cholesterol, blood pressure and family history, to estimate your future heart risk and decide whether treatment like cholesterol-lowering medication is worthwhile. A score of zero is common and reassuring; a higher score is a prompt to discuss prevention with your GP rather than a cause for alarm.
Why your doctor might request a coronary calcium score
- Clarifying heart risk when your doctor is unsure whether to start preventive medication
- A strong family history of early heart disease
- Intermediate heart risk on a standard risk calculation

Referral, Medicare & bulk billing
A calcium score usually needs a referral from your GP or a specialist. It is generally not rebated by Medicare, so you should expect it to be a private scan. The clinic will confirm billing before your appointment. Booking through Radly sends a request, and the clinic confirms the time with you.
