Glossary term · Tests & reports
MRI scan (also: Magnetic resonance imaging, MRI): An MRI scan is an imaging test that uses strong magnets, radio waves and a computer to create detailed pictures of organs and soft tissues.
An MRI scan uses magnets, radio waves and a computer to create detailed pictures inside the body. MedlinePlus notes that MRI does not use X-rays or other radiation. It shows soft tissues clearly, so it is widely used for the brain, spinal cord, nerves, joints and ligaments. Spine, neurosurgery and orthopaedic specialists in India often ask for MRI images.
Is MRI safe with implants?
The magnets are powerful. MedlinePlus says metal objects or implants can interfere with the scan and may be unsafe. Tell the team about pacemakers, artificial joints, other implants or metal fragments. Some tattoo inks contain metal too.
What is the scan like?
- You lie still inside the scanner, usually in a hospital gown.
- The machine is loud. Earplugs or headphones are offered.
- Contrast may be given through a vein for some scans.
- If you feel anxious in enclosed spaces, tell the team. Some centres have open MRI machines.
Who should mention extra details?
MedlinePlus advises telling the team if you have kidney problems or are breastfeeding, especially if contrast may be used.
What can MRI show?
MRI is often used for conditions of the brain, spinal cord, nerves, muscles, ligaments, tendons and joints. It can help tell healthy tissue from unhealthy tissue in many cases.
Sending an MRI
Send the full DICOM study and the report. For spine or joint problems, the surgeon needs to scroll through every sequence.
Questions people ask
Can I fly with an implant that is MRI-safe?
Flying and MRI safety are separate questions. Carry your implant card or details for both airport security and any scan in India. The radiology team checks implant details before an MRI.
Why would a surgeon in India repeat my MRI?
Older scans may not show recent changes, or the sequences may not suit surgical planning. The specialist decides. A recent scan with a clear report helps the first review either way.
