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.

₩280,000
Standalone price

A partner centre's published non-covered price for a 3D cardiac-vessel CT with contrast. (≈$209)

From 1 wk
Earliest slot

One week is the earliest an imaging slot can be held, and there is no referral step before it.

Full written report

English report in your hands in two weeks on average, one week at the soonest and three at the latest. You also get a consultation on preliminary findings on the day of the screening, before you leave.

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. A partner centre 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. A partner centre 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.
