Tests · Cardiac CT angiography

The arteries
themselves, mapped.

A cardiac CT angiogram uses contrast and a fast CT to image the coronary arteries directly, showing narrowing rather than estimating risk from calcium alone. It is the step up from a calcium score, and the partner centres price it as such.

10–15 min
Scan time

Includes a contrast injection and breath holds.

3–7 mSv
Radiation dose

Higher than a calcium score, which is about 1 mSv, and lower than an invasive angiogram.

$197
Standalone price

MediOne's published non-covered price for a 3D cardiac-vessel CT with contrast, ≈₩280,000.

$632
Cheapest program including it

MediOne's Heart program, ≈₩900,000, which lists 3D coronary CT angiography with a carotid ultrasound.

What it finds, and what it does not

What it finds, and what it does not.

The coronary arteries themselves: where plaque sits, how much narrowing it causes, and anatomical variants. It sees non-calcified plaque a calcium score is blind to.

It does not measure whether a narrowing is actually limiting blood flow, which is a functional question answered by stress testing or invasive measurement. It also carries a contrast load and a real radiation dose, so it is not a casual add-on.

Suitability

Who it suits, and who should not have it.

Suits: Adults with an intermediate or high calcium score, chest pain under investigation, or a strong family history who want the arteries mapped rather than scored.

Should not have it: People with significant kidney impairment or a contrast allergy, because of the contrast. Anyone with a zero calcium score and no symptoms, for whom the extra dose usually buys little.

In context

How it differs from the related test.

A calcium score is a cheap, low-dose number. This is a map. Start with the score unless there is a reason not to, and escalate to the angiogram if the score or the symptoms warrant it. MediOne prices both, which makes the escalation a decision rather than a package.

Which tier includes it

Not itemised on any tier.

Not itemised on the three tiers this site prices. MediOne includes it in its Heart program at ≈₩900,000 and prices it standalone at ≈₩280,000; Hanaro's Gold program includes a cardiac calcium score rather than an angiogram. Confirm which of the two your program actually contains.

FAQ

Questions worth asking before you book.

Is this the same as a stent procedure?
No. This is a CT scan through an intravenous line. An invasive coronary angiogram threads a catheter to the heart and is a procedure, not a scan.
Why is the dose higher than a calcium score?
Because it images the vessel lumen through a contrast bolus across the cardiac cycle, which takes more of the scan than a calcium measurement does.
