Cardiac CT / Cardiac MRI (beyond calcium scoring)
Last reviewed 25 August 2026 · Evidence-graded review — see Methodology
Coronary CT angiography uses contrast to visualise the coronary lumen along with both calcified and non-calcified “soft” plaque; cardiac MRI assesses structure, function and tissue characteristics such as scar and fibrosis. CCTA’s real advantage over a calcium score is that it detects non-calcified plaque the score misses entirely, including in younger patients who have not yet developed calcification.
CCTA is well validated for evaluating symptomatic chest pain — the SCOT-HEART trial demonstrated improved diagnostic certainty and reduced coronary death or MI at five years when CCTA was added to standard care — and it is increasingly used to refine risk after a borderline or abnormal CAC score. It is not established as a first-line screening tool for asymptomatic, average-risk adults. It carries contrast and, for CT, radiation exposure that calcium scoring does not, and its evidence base sits in symptomatic or higher-risk populations rather than general population screening.

Not covered in the current review
Singapore’s national screening committee has not reviewed this test in the current volume of its report, which covers nine conditions. That is not a verdict either way.

What you would actually pay
- Healthier SG
- Not subsidised
- MediSave
- Not among the screenings named for outpatient claims

What it costs when it is wrong
- Basis
- No published harm criterion found
- Severity
- Not documented
Not covered in the current volume of the committee’s report, so no harm criterion was found either way.
An empty finding, not a clean bill of health: this means nothing documented was found for this test. It is not a claim that the test is safe.
Screening harm is not only a laboratory question: the committee’s own criteria advise against a test when “the screening test, or follow-up tests arising from a positive screen, are associated with significant medical risks”. Sources on overdiagnosis → · How this is graded.
FAQ
Is the Cardiac CT / Cardiac MRI (beyond calcium scoring) worth doing in Singapore?
The evidence behind Cardiac CT / Cardiac MRI (beyond calcium scoring) is graded moderate for screening an asymptomatic adult. It typically costs S$1,200–2,200 in Singapore. It is ordered on indication only — symptoms, or to further characterise an abnormal CAC score. It is most appropriate for chest pain workup, or further risk characterisation after an elevated CAC score — not routine asymptomatic screening.
