Cardiac CT gives your doctor a precise picture of the arteries that supply your heart. A calcium score is a quick scan, without injections, that measures calcified plaque and helps estimate your future cardiovascular risk. A CT coronary angiogram (CTCA) uses a contrast injection to show narrowings inside the arteries themselves.
Both studies are reported by our on-site Radiologist with subspecialty cardiac CT reporting.
What to expect
- ECG dots are placed on your chest so pictures are timed to your heartbeat.
- For a CTCA, your heart rate may be gently lowered with a short-acting medication so the images are sharp, and a contrast injection is given through a cannula.
- You hold your breath for a few seconds during each acquisition.
- A calcium score needs no injection and only takes a few minutes.
Types we offer
- Calcium score — a quick, injection-free scan that measures calcified plaque burden.
- CT coronary angiogram (CTCA) — contrast-enhanced imaging of the coronary arteries.
How to prepare
| Examination | Typical preparation |
|---|---|
| Both studies | Avoid caffeine (coffee, tea, cola, energy drinks) for 12–24 hours beforehand. |
| CT coronary angiogram | Do not eat for 2–4 hours before; water and usual medications are fine unless we advise otherwise. Tell us about all heart medications. |
| Calcium score | No other preparation needed. |
These are general guidelines — please follow the specific instructions we give you when you book or arrive.
What to bring
- Your referral and your Medicare, concession or DVA card.
- A list of your medications, especially heart and blood-pressure tablets.
- Any previous cardiac imaging or stress-test results.
Your results
Our on-site Radiologist analyses the images and sends a formal report to your referring doctor, who will discuss what the findings mean for your heart-health plan.
Common questions
What is the difference between a calcium score and a CT coronary angiogram?
A calcium score is a quick screening-style scan that counts calcified plaque — no needles. A CTCA uses contrast to show the inside of the arteries and detect narrowings. Your doctor chooses based on your symptoms and risk.
Why do I need to avoid caffeine?
Caffeine raises your heart rate. A slower, steady heartbeat lets us capture sharper images of the moving arteries.
Is the beta-blocker safe?
The small, short-acting dose used to steady your heart rate is very well tolerated. Tell us about asthma or low blood pressure beforehand.
Will my scan be bulk billed?
Calcium scores are usually privately billed (no Medicare rebate). CTCA rebates depend on Medicare criteria — we will confirm your exact cost when you book.
