Preventive imaging · London

Prenuvo-style whole-body MRI, explained honestly.

A 60 to 90 minute, non-contrast, radiation-free scan from brain to pelvis. Genuinely useful for a small number of people. Not a proven screening test, and not a substitute for mammograms, colonoscopy or mpMRI of the prostate. Here is what it actually finds, what it costs across UK providers, and where its limits sit.

The evidence position

Emerging preventive imaging, not proven screening.

NICE does not recommend whole-body MRI as a routine screen for asymptomatic adults. No randomised trial has shown a mortality benefit. Detection rates for incidental findings run to 20 to 40%. Some are genuinely early cancers. Most are not.

  • ~70%

    Essentially normal

    A reassuring baseline. No action beyond routine care.

  • ~20-25%

    Minor incidentalomas

    Benign cysts, small nodules, mild degenerative change. Usually reassurance or one repeat scan.

  • ~5-8%

    Significant findings

    Warrants specialist review, further imaging or biopsy. A small fraction turn out to be early cancer.

What is imaged

Brain to pelvis, in one sitting.

A single scanner session covers most of the body, at screening resolution. Any positive finding usually needs a dedicated organ-specific study to characterise it.

  • Brain and skull base

    Non-contrast structural imaging. Not a substitute for dedicated neuro-MRI when symptoms exist.

  • Cervical, thoracic, lumbar spine

    Screens for lesions and gross degenerative change.

  • Neck nodes and thyroid

    Structural review. Ultrasound remains first line for thyroid nodules.

  • Chest (T1, T2)

    Soft tissue and mediastinal review. Does not replace low-dose CT for lung cancer screening in smokers.

  • Abdomen

    Liver, pancreas, kidneys, adrenals. MRCP sequence for biliary tree.

  • Pelvis

    Prostate, uterus, ovaries, bladder. Not a diagnostic mpMRI prostate study.

  • Lymph nodes

    Enlarged nodes flagged for further characterisation.

  • Bones and soft tissue

    Focal bone lesions and larger soft-tissue masses within the field.

DWI

Diffusion-weighted imaging. Highly sensitive to cellular tumours.

T1

Anatomy, fat, subacute blood.

T2

Fluid, oedema, most pathology.

STIR

Fat suppression, bone marrow and inflammatory change.

MRCP

Non-contrast biliary and pancreatic ducts.

Preparation and the day

What to expect, practically.

Straightforward, painless, and safe for almost everyone. A few implants and devices need clearance in advance.

  • Time on site

    60 to 90 minutes in the scanner, plus safety check-in.

  • Clothing

    Loose, no metal. A gown is provided.

  • Safety screening

    Implants, pacemakers, aneurysm clips, prior surgery all disclosed in advance.

  • Bowel prep

    Occasional light prep or bladder filling for the pelvic component.

  • Hydration

    Normal fluids on the day. No fasting unless requested.

  • Contrast

    Almost always avoided in screening. Added only if a targeted question arises.

UK providers and price

Prenuvo is US only. These are the UK equivalents.

Reporting model, scanner strength and follow-up support vary. We match you based on what actually matters for your case.

Provider Indicative price
Ezra UK £1,900 - £2,800
OneWelbeck Imaging £2,500 - £3,800
HCA Wellington £2,400 - £3,500
London Medical £2,200 - £3,200
InHealth £1,900 - £2,500

Some centres offer sub-specialist double reads at the higher end. Reports usually reach you via a patient portal within 5 to 10 working days, with tiered findings and follow-up recommendations.

Reporting

Read by a specialist. Delivered with follow-up plans.

Screening MRIs are reported by consultant radiologists trained in whole-body imaging. Several UK centres offer a double read for anything ambiguous. The final report is graded, so a benign cyst is not presented in the same voice as a suspicious mass.

Where it does not replace

  • Mammogram

    Breast screening remains X-ray based. Full-body MRI is not a breast MRI.

  • Colonoscopy

    Bowel mucosal disease and polyps require endoscopy.

  • mpMRI prostate

    A diagnostic multi-parametric prostate MRI is a different, more detailed study.

  • Cervical smear

    Cellular screening. Not visible on any imaging test.

Complementary tests

The wider preventive stack.

Whole-body MRI answers structural questions. Cardiovascular risk, bone density and blood-based cancer signals sit alongside it.

Frequently asked

Six things worth understanding before you book.

  • Is whole-body MRI recommended by NICE or the NHS?

    No. NICE does not recommend whole-body MRI as a routine screening test for asymptomatic adults, and there is no randomised trial showing a mortality benefit. It is an emerging preventive imaging option offered privately, and informed consent about its limits is essential.

  • How often will something be found?

    In our experience across UK providers, roughly 70% of scans are essentially normal, 20 to 25% show minor incidental findings that need reassurance or a short-interval repeat, and 5 to 8% show something significant enough to warrant further workup. Genuinely important early cancer detection is uncommon but does occur.

  • What about false positives and anxiety?

    This is the honest downside. Incidental findings can lead to additional scans, biopsies and weeks of uncertainty before a benign result is confirmed. Before booking, decide how you would want to handle an ambiguous finding.

  • Does it use contrast or radiation?

    No ionising radiation. Most screening protocols are non-contrast. Gadolinium is only added if a targeted question arises and your kidney function allows.

  • Is Prenuvo available in the UK?

    Prenuvo is a US company. The closest UK equivalents include Ezra, OneWelbeck, HCA Wellington, London Medical and InHealth, each offering their own whole-body screening protocol on 1.5T or 3T scanners.

  • Does it replace my regular screening?

    No. Whole-body MRI does not replace mammography, cervical smears, bowel screening, mpMRI of the prostate, low-dose lung CT or coronary calcium scoring. Treat it as an addition, not a substitute.
