Whole-body MRI health screening in London
A powerful scan. More useful when a doctor knows why you are having it.
Whole-body MRI can identify abnormalities before they cause symptoms, without using ionising radiation or contrast.
At Coyne Medical, we do not treat a whole-body MRI as a complete health check.
We include it within our Complete and Ultimate health screening programmes, where your scan is considered alongside your medical and family history, cardiovascular risk, blood results, established cancer screening, body composition and fitness.
The aim is not simply to find more abnormalities. It is to find information that could meaningfully change what you do next.

What is whole-body MRI screening?
Whole-body MRI uses strong magnetic fields to create detailed images across multiple areas of the body.
Despite the name, it does not literally scan every part of you. Our screening protocol covers from the top of the head to the pelvis, including the brain, neck, chest, abdomen and pelvis. Arms and legs are not routinely included because evidence suggests the yield from screening asymptomatic limbs is extremely low. The only exception to this is people with a rare inherited cancer gene mutation, TP53.
The scan takes around 90 minutes, uses no ionising radiation and does not require contrast.
Its main role in health screening is to look for potentially important abnormalities, including some cancers, before symptoms develop. But it cannot detect every disease and it does not replace established screening tests.
Whole-body MRI is included within Complete Screening from £5,950 and Ultimate Screening from £7,950. We do not offer it as a standalone health check.
Your doctor assessment takes place at Coyne Medical in Fulham. Whole-body MRI is performed at one of our specialist London imaging partners, selected according to the programme and clinical requirements.
What a whole-body MRI can do
Look across multiple parts of the body
The scan gives detailed structural information across the brain, neck, chest, abdomen and pelvis in one examination.
Detect some cancers before symptoms appear
One of the principal reasons for using whole-body MRI in screening is the opportunity to identify certain tumours while a person still feels well.
Find other clinically important abnormalities
It may also identify non-cancer findings involving neurological, abdominal, musculoskeletal or other systems that warrant further assessment.
Do it without radiation
MRI uses magnetic fields rather than X-rays.
What a whole-body MRI can not tell you
We are big fans of MRI and think it adds real value for our patients. But we only use it as part of a wider health screening assessment. A few examples help explain why we do not recommend it as a standalone test.
A normal brain MRI does not mean you cannot have a stroke
You can have a structurally normal brain scan today and still be at substantial future risk of stroke because of high blood pressure, atrial fibrillation, cholesterol, diabetes or other cardiovascular risk factors.
MRI does not replace assessment and treatment of those risks.
It will not detect cervical cell changes
Whole-body MRI does not replace cervical screening.
Cervical screening is designed to identify high-risk HPV and cell changes before cervical cancer develops, often at a stage when there would be nothing meaningful to see on whole-body MRI.
It cannot tell you whether you have diabetes
Diabetes and prediabetes are diagnosed through metabolic assessment and blood testing.
A scan may sometimes show consequences associated with metabolic disease, such as fatty liver or visceral fat, but it cannot replace glucose, HbA1c and wider metabolic assessment.
It does not replace breast screening
A screening whole-body MRI is different from mammography or a dedicated contrast-enhanced breast MRI.
Which breast imaging is appropriate depends on factors including age, breast density, family history and inherited risk.
It does not replace bowel cancer screening
Small bowel or colorectal cancers and precancerous polyps may not be identified reliably on whole-body MRI.
FIT testing and colonoscopy have different roles and remain important where indicated.
It is not a lung cancer screening CT
For people who meet criteria for lung cancer screening, low-dose CT is the established imaging test.
MRI is not a substitute for it.
This is why we do not sell a normal whole-body MRI as an “all clear”.
Structure is only one part of health. Risk can sit in your blood pressure, your cholesterol, your genes, your metabolism or in changes that require a completely different screening test.
Whole-body MRI can provide valuable information about what is visible structurally today.
Your doctor also needs to understand what may happen tomorrow.
That means looking at cardiovascular risk, cancer screening, inherited risk, metabolic health, fitness and other factors that a scan cannot measure.
The benefit, and the trade-off
Whole-body MRI finds a lot.
A 2020 review of 12 studies involving more than 6,000 asymptomatic people found:
95%
had at least one abnormal finding
30%
had a finding requiring further investigation
1.8%
had a finding where cancer was suspected
1.1%
had a cancer subsequently confirmed
The important point is not that most people have something abnormal on the scan. It is that most abnormalities are not cancer.
That means the quality of the medical interpretation and follow-up matters enormously.
More recent evidence is similar. A 2026 meta-analysis of 9,024 asymptomatic people found confirmed cancer in around 1.6% of those screened
Sometimes the right advice is not to have a whole-body MRI
More imaging is not automatically better medicine.
Whole-body MRI can produce incidental findings that lead to further scans, specialist appointments or biopsies. Most of these ultimately prove benign.
Before recommending MRI, we consider whether:
- you are likely to benefit from screening
- the result could meaningfully change your care
- you have symptoms that would be better investigated with a targeted diagnostic test
- another screening test is more appropriate
- your previous imaging or medical history changes the value of the scan
- you are comfortable with the possibility of incidental findings and further investigations
We are just as comfortable recommending against a scan as recommending one.
Who might benefit from whole-body MRI screening?
Whole-body MRI may be worth considering in people who feel well and want a deeper assessment of hidden disease risk, particularly from around the age of 40, when the likelihood of detecting significant abnormalities rises.
It may also have particular value in some people with increased cancer risk.
But suitability is individual.
Before referral we consider:
- your age
- personal medical history
- family history of cancer
- previous imaging
- current cancer-screening status
- symptoms
- previous or current cancer treatment
- MRI safety and implanted devices
- whether a more targeted investigation would be more useful
If you have symptoms that need investigation, a screening whole-body MRI should not be used instead of the most appropriate diagnostic pathway.
What happens if the MRI finds something?
Our whole-body MRI scans are double reported by established UK consultant radiologists.
Findings are assessed using a structured reporting approach, including the ONCO-RADS framework, which helps categorise findings according to their likelihood of malignancy and whether further investigation is required.
In practical terms:
Low-risk findings
Usually need no further investigation.
Findings that need clarification
May require monitoring or a more targeted investigation such as ultrasound, dedicated MRI or another imaging test.
Higher-risk findings
May require specialist referral, further imaging or biopsy.
Your Coyne Medical doctor reviews the report alongside the rest of your health assessment and explains what the result means for you.
If further investigation is needed, we stay involved rather than simply handing you the scan report.
Does whole-body MRI screening save lives?
What we do not yet know is whether screening the general population with whole-body MRI reduces cancer deaths or improves overall survival.
There have not yet been sufficiently large, long-term studies to demonstrate that.
That distinction matters.
We therefore use MRI as an additional screening tool, not as a replacement for established cancer screening and not as a guarantee that cancer has been excluded.
MRI versus CT for health screening
MRI and CT answer different medical questions.
Whole-body MRI uses magnetic fields and therefore involves no ionising radiation.
CT uses X-rays and therefore does involve radiation exposure. That does not make CT a bad test. In some situations it is the better test, including low-dose CT lung screening in eligible smokers and coronary CT imaging when cardiovascular assessment indicates it.
Our approach is not to choose the test that scans the most body parts.
It is to choose the investigation that best answers the clinical question.
Why we include MRI within a wider health assessment
Whole-body MRI can tell us a great deal about structure.
It cannot tell us everything about risk.
That is why Complete Screening combines whole-body MRI with:
- a 90-minute doctor assessment
- advanced blood testing
- detailed cardiovascular risk assessment, including lipoprotein(a)
- established cancer screening according to age and risk
- MRI body composition
- laboratory VO₂ max testing
- metabolic assessment
- review of family history and inherited risk
- a personal doctor who brings the findings together and remains involved throughout the year
One scan. One part of a much bigger health picture.
Want to understand inherited risk as well?
Ultimate Screening adds inherited cancer genetic testing, pharmacogenomics and further assessment.
A scan does not make decisions. Your doctor does.
A radiology report can tell you what has been seen.
It cannot decide how important that finding is in the context of your health.
With Complete and Ultimate, your personal doctor considers the MRI alongside your blood results, medical history, family history, cancer screening, cardiovascular risk, metabolic health and fitness.
If something needs further investigation, treatment or monitoring, we remain involved throughout the year.

What Our Patients Say
Frequently Asked Questions
Our whole-body MRI screening protocol covers from the top of the head to the pelvis, including the brain, neck, chest, abdomen and pelvis.
The limbs are not routinely included in asymptomatic screening because the evidence suggests they have extremely low diagnostic yield.
No.
MRI uses magnetic fields and radiofrequency energy rather than the ionising radiation used in CT and X-rays.
At Coyne Medical, whole-body MRI is not offered as a standalone health check.
It is included within our Complete Screening programme from £5,950 and Ultimate Screening programme from £7,950.
Both programmes combine MRI with a broader doctor-led assessment, including blood tests, established cancer screening, cardiovascular and metabolic risk assessment and medical follow-up.
MRI is not suitable for everyone.
You may not be able to have an MRI if you have certain implanted medical devices, metal fragments or other contraindications identified on the MRI safety questionnaire.
We would also usually avoid screening whole-body MRI during pregnancy.
If you have recently had surgery, have previously had cancer treatment or are currently under specialist care, we may recommend a more targeted investigation instead.
Suitability is reviewed before referral.
Many people with mild claustrophobia are still able to complete an MRI scan.
If you are concerned, let us know before the appointment. We can discuss what the scan involves and whether additional support or an alternative approach would be more appropriate.
The scan takes around 90 minutes, so it is important that you feel comfortable with the process before proceeding.
No. Our standard whole-body MRI screening protocol is performed without contrast.
It can detect some cancers and potentially identify them before symptoms develop, but it cannot detect every cancer.
It does not replace established breast, cervical, bowel or lung cancer screening where these are appropriate.
No.
A normal MRI tells us that no significant structural abnormality was identified on the areas examined.
It does not exclude cardiovascular risk, diabetes, inherited cancer risk or diseases detected using other screening methods.
For example, someone can have a normal brain MRI but still be at high future risk of stroke because of untreated high blood pressure.
No.
We consider it particularly from around age 40, but the decision depends on your health, family history, previous tests, screening status and what information would actually be useful.
Your scan is double reported by UK consultant radiologists and reviewed by your Coyne doctor.
Depending on the finding, the right next step may be no action, monitoring, additional imaging, specialist referral or further investigation.
There is no single recommended interval for whole-body MRI screening in people who are otherwise well.
The decision to repeat a scan depends on factors including your age, medical and family history, previous findings and whether repeating the scan is likely to add useful information.
We do not recommend repeating whole-body MRI automatically every year for everyone.
If a previous scan has identified a finding that needs surveillance, the timing of follow-up imaging will be based on that specific finding.
No.
MRI is an imaging test. It cannot measure many of the things that determine future health risk, including blood pressure, cholesterol, lipoprotein(a), blood glucose, fitness or inherited genetic risk.
At Coyne Medical it forms one part of our Complete and Ultimate screening programmes.
At Coyne Medical, whole-body MRI is offered within our Complete and Ultimate health screening programmes rather than as a standalone health check.
Yes, if mammography is recommended for you.
A whole-body MRI is not the same as dedicated breast imaging and does not replace mammography or a breast MRI performed specifically to assess breast tissue.
Which breast screening is appropriate depends on factors including your age, breast density, family history and inherited risk.
At Coyne Medical, we consider breast screening separately rather than assuming a normal whole-body MRI means no further breast screening is needed. We routinely arrange mammogram screening from 40 years of age for average risk females. Some patients, for example, those with extremely dense breast tissue may also benefit from supplemental breast ultrasound or dedicated breast MRI scans.
