MRI: What to Expect

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.
