DIAGNOSTIC OVERVIEW

What CTCA Heart Scan Is

Where a calcium score gives a single number, a CTCA produces detailed images of the coronary arteries. It uses a contrast dye to make the vessels clearly visible, allowing assessment of both calcified and non-calcified plaque as well as vessel structure. It is a more comprehensive cardiac scan, used when a fuller picture is warranted.

Why it's worth it

Sees soft plaque a calcium score can't.

The deepest non-invasive look at your arteries.

Specialist-reviewed, clearly explained.

DIAGNOSTIC DETAILS

What it measures

The scan assesses coronary plaque, narrowing of the arteries and vessel structure, drawing on detailed images of the coronary arteries.

Get started with Precursor

Plaque, Hard and Soft

The scan images both calcified plaque and the softer, non-calcified plaque a calcium score cannot see. That soft plaque is often the more unstable kind, so imaging it directly gives a fuller, earlier read on your true coronary risk.

Detailed 3D Imaging

High-resolution images of the coronary arteries, not just a single summary number.

Narrowing and Structure

Detailed three-dimensional images show any narrowing of the arteries and the structure of the vessels themselves. It is the closest thing to looking inside your coronary arteries without an invasive procedure, reviewed by a specialist.

"A CTCA lets us see the arteries in real detail, including the softer plaque simpler tests miss. For the right patient, that depth turns uncertainty into a clear, actionable picture."

FAQs

Your Questions, Answered

How do I book a test?

Choose your test and a time that suits you online, then visit one of our partner locations. If any preparation is needed, such as fasting, we tell you clearly when you book.

When and how do I get my results?

Your results appear in the Precursor app once your sample or scan has been processed, laid out in plain language rather than a wall of numbers. Turnaround depends on the test, and we give you a timeframe when you book.

Will someone explain my results to me?

Yes. A clinician reviews your results, flags anything worth your attention and helps you understand what they mean and what, if anything, to do next. You are never left to interpret them alone.

Where can I get tested?

We operate nationally through a network of partner locations across most major cities and regional centres. When you book, you simply choose the location that is most convenient for you.

Do I need to prepare or fast beforehand?

It depends on the test. Some require fasting or other simple preparation, and others need nothing at all. Whatever applies, we tell you clearly at the time you book so there are no surprises on the day.

Can I track my results over time?

Yes. The Precursor app is built to show change between tests, so each result becomes a trend you can follow rather than a one-off snapshot. Retesting lets you see the effect of any changes you make.

How is my data handled and kept private?

Your health data is handled with care and kept private. Results are stored securely in the Precursor app and shared only with you and the clinicians involved in your care.

What happens if something needs further attention?

If your results surface something worth acting on, your clinician explains it calmly and talks you through sensible next steps. The aim is early clarity and considered action, never unnecessary alarm.
