An MRI (magnetic resonance imaging) scan uses a powerful magnetic field and radio waves to create detailed pictures of the inside of your body. Unlike X-rays or CT scans, there's no radiation involved — but the magnet is powerful enough that preparation matters.
On the day of your scan, wear comfortable clothing without metal fasteners, zippers, or underwire. Most imaging centers will give you a gown if needed. Leave jewelry, watches, and hair clips at home or in your locker.
You can usually eat and drink normally before the scan unless your doctor specifies otherwise. If contrast dye is required, you may be asked to fast for 4 hours beforehand. Your coordinator will confirm this with the facility.
The scan itself typically takes 20–60 minutes. You'll lie still on a padded table that slides into the scanner. The machine makes loud knocking sounds — headphones or earplugs are provided. If you're claustrophobic, ask about open MRI options or mild sedation in advance.
After the scan, you can resume normal activities right away. Results are typically read by a radiologist within 24–48 hours and sent to your referring doctor. Your NORTON coordinator will follow up to make sure the report reaches the right person.
