MRI: What to Expect
What is an MRI?
MRI (Magnetic Resonance Imaging) is a non-invasive test that uses powerful magnets and radio waves to create detailed images of the body's organs, bones, and soft tissues. Unlike X-rays or CT scans, MRI does not use radiation.
Why is an MRI Needed?
Your doctor may order an MRI to:
✔ Diagnose joint, muscle, or ligament injuries
✔ Detect tumors, infections, or nerve issues
✔ Evaluate spinal conditions (herniated discs, pinched nerves)
✔ Assess brain function or neurological disorders
Before the MRI
✔ Wear loose, comfortable clothing (avoid metal zippers or buttons).
✔ Remove all metal objects (jewelry, watches, hearing aids, glasses).
✔ Inform your doctor if you have:
- A pacemaker, metal implants, or artificial joints
- A history of kidney problems (if contrast dye is needed)
- Claustrophobia (you may need a mild sedative)
✔ Eat normally unless instructed otherwise (fasting is only required for certain MRIs).
During the MRI
✔ You will lie on a cushioned table that slides into a tunnel-shaped machine.
✔ Remain as still as possible for clear images.
✔ You may hear loud knocking or buzzing sounds—earplugs or headphones will be provided.
✔ Some MRIs require contrast dye (gadolinium) to enhance images, which is given through an IV.
✔ The scan usually takes 30-60 minutes.
After the MRI
✔ You can resume normal activities immediately unless sedated.
✔ If contrast was used, drink plenty of water to flush it out.
✔ Your doctor will review the images and discuss results at a follow-up visit.
When to Call Your Doctor
🚨 If you experience allergic reactions to contrast dye (itching, rash, swelling)
🚨 If you feel dizzy, weak, or have trouble breathing after the MRI
🚨 If you have pain or redness at the IV site (if contrast was used)
Bottom Line
✔ MRI is safe and painless but requires lying still.
✔ Remove all metal objects before the scan.
✔ Discuss concerns (claustrophobia, metal implants) with your doctor beforehand.
✔ Expect results within a few days after your doctor reviews the images.
