Your guide to Full body MRI
A broad scan with important screening limitations. What to expect, how to prepare and what to ask before booking.
Last reviewed 7 Oct 2026 · Information onlyWhat is it?
Full body MRI examines several body areas using magnetic fields and radio waves. What is covered differs between providers; it is not a complete check for every disease.
What is it used for?
Some providers offer it for general screening. Routine full body MRI for people without symptoms is not an NHS population screening programme. Discuss possible benefits, limitations and follow up before booking.
How does it feel and how long does it take?
You lie inside the scanner for a longer examination, often around 60 to 90 minutes. Time and areas covered vary. Noise and keeping still can be challenging.
How should I prepare?
Ask which areas and sequences are included, whether contrast is used and how unexpected findings are handled. Follow the centre’s fasting and MRI safety instructions.
Who needs extra safety checks?
MRI implant and metal screening still applies. Screening may find uncertain abnormalities, cause anxiety and lead to unnecessary tests. A normal scan cannot rule out all illness and must not delay assessment of symptoms.
A scan is not a substitute for clinical assessment. A normal result does not rule out every condition. Partner clinics include a clinician or GP call before the scan to confirm the right test.
