Calcium Score vs. CTA: Which heart scan do you actually need?
Calcium Score vs. CTA: Which heart scan do you actually need?
A $250 calcium score gives you a number. A CT angiogram shows you your arteries. Here’s when one is enough — and when it isn’t.
If your doctor mentioned a heart scan — or you’ve been reading about calcium scores online — you’ve probably noticed there are several options at very different price points. They aren’t the same test, and they don’t answer the same question. Here’s a clear, no-jargon breakdown of what each one actually sees.

What a calcium score sees
A coronary calcium score is a 15-minute CT scan with no contrast and no IV. It produces a single number — the Agatston score — that measures the amount of calcified plaque in your coronary arteries. Higher number, higher cardiovascular risk. It’s a useful entry point for someone with no known risk factors who wants a baseline, or for deciding whether to start a statin. At CPAI, it’s a flat $250 — no insurance prior-auth, no referral required.
What a CT angiogram adds
A coronary CT angiogram (CTA) goes further. Using IV contrast and a 640-slice scanner that captures your heart in a single heartbeat, it produces vessel-by-vessel images of your coronary arteries — showing not just calcified plaque, but soft plaque, the kind a calcium score cannot see. That distinction matters: most heart attacks in people under 60 are caused by soft, unstable plaque. A calcium score of zero doesn’t always mean clean arteries. A CTA shows what’s actually there.
A calcium score tells you if there’s calcified plaque. A CT angiogram tells you what’s there, where it is, and how much of your artery is affected. For most patients who are concerned enough to come in, the CTA is the scan that actually answers the question.
Which one is right for you
If you’re under 40 with no symptoms and no family history, a calcium score is a reasonable starting point. If you’re 40 or older, have a family history of heart disease, or have any concerning symptoms, a CTA is what most physicians recommend — and what most of our patients choose. For the most comprehensive analysis available, including AI-powered rupture-risk scoring on every plaque, there’s also Cleerly Plaque Analysis. All three are flat-fee, performed on an open-ring scanner (no claustrophobic tube), with reports delivered within 48 hours.
