Prices vary by clinic, time of day, scanner field strength (1.5T vs 3T), and whether contrast is used.
The problem
Higher field strength is not always the right answer.
A 3T scanner gives more detail, but 1.5T is sometimes safer, more comfortable or simply enough. Matching the field strength to your question - and reading it well - is what turns a scan into an answer.
-
Want the sharpest image?
For brain, spine, prostate and small joints, 3T is often preferred.
What it shows
When each field strength is right.
Both scanners are excellent - but for some questions one clearly fits better. Here is how the choice is usually made.
-
3T for brain & spine
The extra resolution of 3T helps for the brain, spine and subtle neurological questions.
-
3T for prostate mpMRI
Prostate mpMRI is usually best on 3T, where fine detail can change the PI-RADS score.
-
3T for small joints
Wrist, ankle and other small-structure imaging benefit from the sharper 3T picture.
-
1.5T with certain implants
For some pacemakers and implants, 1.5T is the safer or clearer choice.
-
1.5T wide-bore for comfort
Wide-bore 1.5T scanners suit larger or more anxious patients.
-
1.5T for general body imaging
Well-established and perfectly capable for most routine body scans.
-
Either works for most scans
For many everyday scans, both give an excellent, diagnostic result.
The practical differences
How 3T and 1.5T actually differ.
What each option on your referral is actually for.
-
Image detail
3T gives a sharper picture; 1.5T is still excellent for most scans.
-
Scan time
3T can be a little faster for some sequences, but both are comparable.
-
Implant compatibility
Some implants are safer or clearer on 1.5T, so implant status is always checked first.
-
Artefact & noise
3T can show more artefact near metal; 1.5T is often more forgiving.
-
Bore & comfort
Wide-bore versions exist at both field strengths for space and calm.
-
Availability
1.5T is more widely available; 3T is concentrated in specialist centres.
-
Cost
3T is sometimes a small premium, but not always.
-
Best-for
Brain, spine, prostate and small joints lean 3T; general body works well on 1.5T.
Safety and eligibility
One of the safest tests in medicine.
-
Pacemakers, defibrillators, neurostimulators
Many modern devices are MR-conditional, and field strength can matter.
-
Aneurysm clips and vascular coils
Model and date of insertion matter. Your hospital can supply this information.
-
Metal implants and artefact
1.5T is often more forgiving near metalwork, and the field strength is chosen accordingly.
-
Metal fragments (eye, shrapnel)
May need a prior orbit X-ray.
-
Pregnancy
No ionising radiation at either field strength. Contrast avoided unless essential.
-
Kidney function
A recent eGFR is needed if gadolinium contrast is planned.
-
Weight and size
Most scanners accommodate up to 200 kg. Wide-bore options for larger patients.
Reading your report
A report can look intimidating. It isn't.
Whatever the field strength, the report keeps to the same four parts.
A quiet reminder
The report is written for your doctor, not for you - and that is normal.
Ask the clinician who requested the test to talk you through it before your follow-up.

Frequently asked
Common questions about 3T vs 1.5T MRI.
Quick answers on cost, referrals, contrast, claustrophobia and results.
-
Is 3T always better than 1.5T?
No. 3T gives more detail for the brain, spine, prostate and small joints, but 1.5T is excellent for most scans and is sometimes the better choice - especially with certain implants.
-
Is a 3T MRI safe?
Yes. Both 3T and 1.5T are very safe, with no ionising radiation.
-
Does a 3T scan cost more?
Sometimes there is a small premium, but not always.
-
Which is better for a prostate MRI?
Prostate mpMRI is usually best on 3T, where the extra detail can change the PI-RADS score. Prostate scans are usually booked accordingly.
-
I have an implant - which should I have?
It depends on the exact device. Some are safer or produce fewer artefacts on 1.5T.
-
Is 1.5T outdated?
Not at all. 1.5T is a modern, well-established standard that produces excellent diagnostic images for the vast majority of scans.
-
Which is quieter or faster?
They are broadly similar. 3T can be marginally faster for some sequences; both use headphones for the noise.
-
How do I know which one I had?
It is stated on your report and images. If you are unsure, the radiology department that performed the scan can confirm it.
-
Do I need a referral?
Most scans accept self-referral.
-
How quickly will I get results?
A consultant radiologist report is usually ready in 24-72 hours. With your consent, the report and images can be shared with your GP or specialist.
