Your guide to MRI
Detailed images of joints, organs and soft tissues. What to expect, how to prepare and what to ask before booking.
Last reviewed 7 Oct 2026 · Information onlyWhat is it?
MRI uses a strong magnetic field and radio waves to create detailed pictures inside the body. It does not use ionising radiation.
What is it used for?
A clinician may consider MRI for problems affecting the brain, spine, joints or other soft tissues. Symptoms alone cannot determine the right scan.
How does it feel and how long does it take?
You lie on a bed inside a scanner. It is noisy, so ear protection is provided. You need to keep still. Many scans take 15 to 90 minutes, depending on the area and protocol.
How should I prepare?
Follow your centre’s instructions about food, drink and medicines. Remove jewellery and metal items. Tell the team if you feel anxious in enclosed spaces.
Who needs extra safety checks?
Tell the team about any pacemaker, implant, metal fragment, kidney condition or possible pregnancy. Some implants are compatible under specific conditions, but the scanning team must check. Contrast is not needed for every scan.
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.
