Quick Answer: Private Cardiac MRI
A private cardiac MRI in the UK typically costs £700–£1,200 (contrast and stress-perfusion scans at the upper end; London specialist centres sometimes higher), takes 45–90 minutes, and is available privately within days. It uses strong magnets and radio waves — no ionising radiation — to image the heart muscle, chambers, valves and major vessels, and it’s the leading test for tissue characterisation (scar, inflammation, cardiomyopathies).
One important nuance: cardiac MRI doesn’t map the coronary arteries the way a CT coronary angiogram does — it shows the consequences of poor blood flow (scar, and, under stress, under-perfused muscle). You’ll usually need a specialist referral. Most insurers cover it when a specialist requests it. Compare Providers.
What this guide covers
What Is a Cardiac MRI?
A cardiac MRI — also called cardiac magnetic resonance (CMR) — uses strong magnets and radio waves to capture detailed still and moving images of the heart. Unlike a CT scan, it uses no ionising radiation. It’s non-invasive and painless, performed while you’re awake without anaesthetic, and produces images of the heart’s chambers, muscle (myocardium), valves and the major vessels carrying blood to and from it.
It’s often not the first heart test — an echocardiogram (ultrasound) is usually first-line for valves and overall function, and a resting ECG or event monitor for rhythm. Cardiac MRI comes in when more detailed tissue characterisation or precise measurements are needed. It’s one part of the wider heart-check picture — see our private heart health check guide.
What Does a Cardiac MRI Show?
CMR is prized for tissue characterisation — seeing not just the shape of the heart but the state of the muscle itself:
Function
How well the heart pumps, with precise chamber volumes and ejection fraction.
Scar & damage
Areas of scarring, e.g. after a previous heart attack (shown by late gadolinium enhancement).
Inflammation
Myocarditis and other inflammatory conditions of the heart muscle.
Cardiomyopathies
Dilated, hypertrophic and restrictive cardiomyopathy — a key CMR strength.
Valves & vessels
Valve function and the major vessels, including the aorta.
Congenital
Structural and congenital heart abnormalities, in detail.
Does a Cardiac MRI Show Blockages?
ℹ️ The honest, precise answer
Not directly, in the way people often expect. Cardiac MRI does not map the coronary arteries the way a CT coronary angiogram does. What it shows is the consequences of reduced blood flow: scar from a previous heart attack, and — using a stress perfusion protocol — regions of heart muscle not receiving enough blood under stress. So it answers “has the muscle been damaged, and is any area starved of blood?” rather than “exactly where are the arteries narrowed?”. If mapping the coronary arteries themselves is the priority, a CT coronary angiogram is often the better test — your cardiologist will recommend the right one for your symptoms.
How Much Does a Private Cardiac MRI Cost? (2026)
| Scan type | Typical UK private cost (2026) |
|---|---|
| Standard cardiac MRI | £700–£950 |
| With gadolinium contrast | £850–£1,200 |
| Stress perfusion CMR | £1,000–£1,200+ |
| London specialist centres | Can exceed £1,200–£1,500 |
Indicative ranges — prices vary by hospital, scanner (1.5T vs 3T), protocol length and whether a cardiologist provides an extended opinion. Always ask whether the fee includes the consultant report and any contrast or stress agent — these are sometimes billed separately. Compare with other scans in our regional guides such as private MRI London and Manchester, other scan types like brain MRI, knee MRI and prostate mpMRI, and see how contrast affects cost.
How Long Does a Cardiac MRI Take?
Allow 45–90 minutes. Simple structural scans sit at the shorter end; stress perfusion protocols push toward the upper end. You lie still on a padded bed that slides into the scanner (open at both ends), and you may be asked to hold your breath briefly at points to sharpen the images. Contrast, if used, goes in via a small cannula in the arm. The scanner is noisy — you’ll be offered ear protection, and many centres offer music.
ℹ️ Getting your results
A consultant radiologist or cardiologist reviews the images and writes a report. Cardiac MRI often needs sub-specialty reporting, so turnaround is typically 48–72 hours rather than same-day — see how private scan reports are reviewed.
Contrast, Stress Protocols & Safety
- Gadolinium contrast — often used to reveal scar (late enhancement) or inflammation, injected via a cannula. It’s not required for every protocol. See MRI contrast explained.
- Stress CMR — a pharmacological stress agent mimics exercise so the scan can assess blood flow to the heart muscle. This is what lets CMR flag under-perfused (potentially ischaemic) areas.
- Safety — CMR is generally very safe with no ionising radiation. The main considerations are MRI-unsafe implants, severe claustrophobia, significant kidney impairment (affecting contrast use), and rare contrast reactions.
⚠️ Implants & claustrophobia — declare early
Always declare a pacemaker, ICD or any metal implant — some devices are “MRI-conditional” and can be scanned under strict protocols, but the imaging team must confirm safety first. If you struggle with enclosed spaces, ask about open MRI options — though note cardiac protocols may need a specific scanner, so confirm availability. The team screens everyone with a metal-safety questionnaire before the scan.

Insurance & Referrals
Cardiac MRI usually needs a specialist referral (cardiologist or GP) — unlike routine MSK scans you often can’t simply self-refer, because the protocol is tailored to your suspected condition. Some centres can arrange an in-house cardiology assessment to issue one.
The insurance honesty split
Already insured, and this is a new investigation? Most UK policies cover cardiac MRI when a specialist requests it as part of an approved claim — subject to your outpatient limit, referral and pre-authorisation. Buying cover now, after a heart condition or symptoms have appeared? A new policy will usually exclude it as pre-existing — self-pay is available nationwide in that case. See how to get a private referral and GP referrals for private MRI.
How to Book a Private Cardiac MRI
- Consultation — a private GP or cardiologist confirms CMR is the right test (vs echo, CT angiogram or another scan)
- Choose a centre — private hospitals with cardiac MRI capability (1.5T/3T); ask about experience with your indication (e.g. myocarditis vs stress perfusion)
- Referral & authorisation — obtain the referral; if insured, get pre-authorisation first
- Prep & scan — you’ll get instructions (fasting if a stress test, medication notes, the metal-safety questionnaire); allow 45–90 minutes on the day

Frequently Asked Questions
How much does a private cardiac MRI cost in the UK?
A private cardiac MRI in the UK typically costs around £700–£1,200 in 2026, with contrast-enhanced or stress-perfusion scans at the upper end and London specialist centres sometimes higher. Always check whether the fee includes the consultant cardiologist or radiologist report and any contrast or stress agent, as these are sometimes charged separately.
How long does a cardiac MRI take?
A cardiac MRI usually takes around 45–90 minutes. Simple structural scans are at the shorter end, while stress perfusion protocols, which assess blood flow to the heart muscle under stress, push the total time toward the upper end. You lie still on a bed that moves into the scanner and may be asked to hold your breath briefly at points.
Does a cardiac MRI show blockages?
Not directly in the way a CT coronary angiogram maps the coronary arteries. A cardiac MRI shows the consequences of reduced blood flow — areas of scar from a previous heart attack, and, using a stress perfusion protocol, regions of heart muscle not getting enough blood. If mapping the coronary arteries themselves is the priority, a CT coronary angiogram is often the better test, and your cardiologist will advise.
What does a cardiac MRI show?
Cardiac MRI gives detailed images of the heart muscle, chambers, valves and major vessels. It excels at tissue characterisation — detecting inflammation (myocarditis), scarring, and cardiomyopathies (dilated, hypertrophic, restrictive) — and measures how well the heart pumps with precise chamber volumes. It can also assess congenital heart conditions and, with a stress agent, blood flow to the heart muscle.
Do I need a referral for a private cardiac MRI?
Usually yes. Unlike routine MSK scans, cardiac MRI normally needs a referral from a cardiologist or GP, because the scan protocol is tailored to your suspected condition. Some private centres can arrange an in-house cardiology assessment to issue a referral if appropriate. If you are claiming on insurance, you will also need pre-authorisation.
Does a cardiac MRI use contrast, and is it safe?
Many cardiac MRI protocols use a gadolinium contrast agent given through a small cannula to highlight scar (late enhancement) or inflammation, though it is not needed for every scan. Cardiac MRI is generally very safe and uses no ionising radiation. The main considerations are MRI-unsafe implants, severe claustrophobia, significant kidney impairment affecting contrast use, and rare contrast reactions — the imaging team screens for all of these.
Does health insurance cover cardiac MRI?
Most UK private health insurance policies cover cardiac MRI when it is requested by a specialist as part of an approved claim, subject to your outpatient limit, referral and pre-authorisation. If your symptoms or heart condition pre-date a new policy, it may be excluded as pre-existing — in which case self-pay is available nationwide. Always confirm cover and get authorisation before booking.
