What happens at a doctor-led MRI screening assessment?
A doctor-led MRI screening assessment starts with a consultation that decides whether a scan will help you and which scan is right. The doctor completes the safety checks and writes the referral, a consultant radiologist reports the images, and the doctor explains the result as a clear answer and plan. The Online GP by The Wellness runs this pathway from Marylebone.
Key points
The Royal College of Radiologists does not advise scans without a clear medical indication, which is why a doctor's assessment before imaging matters.
A single-area private MRI in London typically costs £580 to more than £950 in 2026, and full-body MRI £1,500 to more than £3,500.
Incidental findings are common on screening MRI, so an agreed plan for follow-up before the scan avoids unnecessary worry.
Most MRI scans take 15 to 60 minutes, use no radiation and need little preparation.
The Online GP by The Wellness quotes MRI fees per patient and confirms them on WhatsApp before booking.
Why start with a doctor rather than a scan?
Starting with a doctor means the scan answers a real question. The doctor reviews your symptoms, family history, previous results and goals, then decides whether imaging is likely to help, which area to scan, and whether a blood test or a different scan would be more useful. Sometimes the right answer is no scan at all.
The Royal College of Radiologists does not advise people to have whole-body scans without a clear medical indication, its president told Medscape News UK in 2026. A doctor-led assessment applies that principle to each person.

What happens step by step?
A doctor-led MRI screening assessment at The Online GP by The Wellness follows five steps. The doctor assesses you, the safety and referral forms are completed, the scan takes place at a partner imaging centre, a consultant radiologist reports it, and the doctor explains the result.
Consultation. A GMC-registered doctor takes your history and agrees whether a scan is right and which one.
Safety and referral. You complete an MRI safety questionnaire, and the doctor writes the referral with the clinical question.
Scan. You attend a partner imaging centre in London for the MRI, usually within days.
Report. A consultant radiologist reads the images and writes a formal report.
Results. The doctor explains the findings in plain language and agrees a plan, including any follow-up.
"The report is written for doctors," says Dr Adel Elalfy, Head of Primary Care at The Online GP by The Wellness. "What patients want is an answer. Our job is to turn the radiologist's report into a clear explanation and a plan they can act on."
What scans can a screening assessment lead to?
A screening assessment can lead to a targeted MRI of one area, such as the prostate, liver, heart, brain, spine or pelvis, or to a whole-body MRI where that suits your risk. The doctor may also recommend ultrasound, CT or blood tests instead, depending on the question.
A man with a raised PSA usually needs a prostate MRI. A person with a family history of liver disease may need a liver scan with fat measurement. Someone with an inherited cancer syndrome may need a whole-body MRI each year.
Our guides to whether a whole-body MRI is worth it and choosing between MRI, CT and ultrasound explain the options.
How are incidental findings handled?
Incidental findings are handled with a plan agreed before the scan. The doctor explains that harmless findings are common, which ones would need follow-up, and how they would be managed. After the scan, the doctor reviews each finding, explains what it means and arranges only the follow-up that is genuinely needed.
A 2026 radiology review on screening whole-body MRI reports incidental findings in up to 97% of screening scans. Clear reporting and a doctor who knows your history keep those findings in proportion.
How should I prepare for an MRI scan?
Most MRI scans need little preparation. You complete a safety questionnaire, remove metal objects, and may be asked not to eat for a few hours before abdominal or pelvic scans. Tell the team about pacemakers, implants, metal fragments, pregnancy, kidney problems and claustrophobia.
Scans usually take 15 to 60 minutes. The scanner is noisy, so you wear ear protection. Some scans use an injection of contrast dye to show certain tissues more clearly. Ask about preparing for your scan on WhatsApp.
How much does a doctor-led MRI screening assessment cost?
Full-body MRI in the UK typically costs £1,500 to more than £3,500, and a single-area private MRI in London £580 to more than £950, according to WeCovr's 2026 MRI cost guide. At The Online GP by The Wellness, the assessment consultation starts with a classic GP appointment from £150.
MRI scans are quoted per patient from the clinic's imaging partner list, and the team confirms the fee before booking. For a wider plan, the Executive Physical starts from £2,995. Book a doctor-led MRI assessment on WhatsApp.
Can a doctor tell me if I need a scan at all?
Yes. The Online GP by The Wellness offers a free suitability review. Send your age, symptoms, family history and any previous scans on WhatsApp. A doctor either approves you for an assessment or tells you plainly that a scan is unlikely to help right now.

Frequently asked questions
Do I need a referral for a private MRI?
Yes. A private MRI needs a referral from a doctor who states the clinical question. The Online GP by The Wellness doctor writes the referral after the assessment.
How quickly can I have a private MRI?
Most private MRI scans in London take place within days of referral, and reports usually follow within a few working days.
Can I have an MRI if I am claustrophobic?
Often, yes. Wider-bore scanners, music, feet-first positioning and short scan protocols help many people. Tell the team in advance so they can plan.
Will I get a copy of my MRI report?
Yes. You receive the consultant radiologist's report and the doctor's explanation, which you can share with your registered GP.
