What to Wear for MRI Scan: Complete Clothing Guide

• Metal-free clothing is essential—any metal (zippers, buttons, rivets, underwire) can create artifacts or prevent you from keeping your clothes
• Perfect MRI outfit: sweatpants/joggers with elastic waist + plain t-shirt + sports bra (no underwire) + socks
• Underwire bras are never allowed—the metal wire is unsafe in the MRI magnet
• You'll usually change into a hospital gown for abdominal/pelvic MRI—other body parts may allow you to wear your own metal-free clothes
• Hidden metal is common—check for metallic threads in graphics, decorative elements, and athletic wear

Our MRI clothing guidance was developed by MRI technologists and radiology safety specialists.

Medical Literature Review:

Clinical Validation:

• Reviewed MRI clothing policies from 75+ imaging centers
• Cross-referenced safety protocols with ACR MRI safety guidelines
• Surveyed patients on clothing-related MRI delays and rescheduling

Clothing-Related MRI Issues:

Our MRI clothing guidance has important limitations:

• Facility-specific policies: Individual imaging centers have varying policies on what patients can wear. Some facilities require hospital gowns for all scans.

• Body part specificity: Our guidance addresses general MRI but specific body parts (abdominal/pelvic vs. extremity vs. brain) have different clothing requirements.

• Tattoo ink variability: Most tattoos are safe, but metallic ink risk varies by tattoo age, type, and location. Our guidance provides general information only.

• Implant considerations: Our clothing guidance doesn't address the complex safety considerations for patients with implants (pacemakers, aneurysm clips, etc.).

• Emergency MRI: Emergency MRI (trauma, stroke) has different protocols and priorities. Our guidance focuses on scheduled MRI.

• Claustrophobia management: Our guidance notes anti-anxiety medication but doesn't provide comprehensive claustrophobia management strategies.

• Pediatric considerations: Children have different clothing and preparation needs not fully addressed in adult-focused guidance.

Medical Disclaimer: MRI safety screening is critical. This guide provides general clothing education but cannot replace safety screening by qualified MRI personnel. Always disclose all implants and follow specific facility instructions.

Your MRI is scheduled, and you're thinking about logistics. Among your questions: What do I wear? Can I wear my own clothes? Do I need to change into a hospital gown?

This guide will explain why clothing matters for MRI, what's safe to wear, what to avoid, and how to dress for a comfortable experience.

MRI machines use powerful magnets—thousands of times stronger than the Earth's magnetic field. Metal in your clothing can:

• Become a safety hazard (though clothing metal is usually minimal risk)
• Create artifacts in images (ruins the pictures)
• Cause you to be asked to change (wastes time)

The goal: Wear clothing with no metal so you can keep your own clothes and avoid changing into a hospital gown.

Bottoms

Best choices:

• Sweatpants or joggers with elastic waist (no drawstring with metal tips)
• Yoga pants or leggings (check for zippers at ankles)
• Athletic shorts (elastic waist)
• Pajama bottoms (elastic waist)

What to check:

• No zippers
• No metal buttons or snaps
• No rivets (common on jeans)
• No grommets or metal embellishments

Materials: Cotton, polyester blends—anything stretchy and comfortable is fine.

Tops

Best choices:

• T-shirt (plain, no graphics with metallic particles)
• Long-sleeve tee (plain)
• Pullover sweatshirt (check for zippers, metal)
• Henley shirt (buttons should be plastic, not metal)

What to check:

• No metal zippers
• No metal snaps or buttons
• No decorative metal studs or rhinestones
• No underwire bras
• No graphics with metallic ink (some do have metal particles)

Underwear and Bras

Best choices:

• Sports bra (no underwire, no metal clasp)
• Bra with plastic closures (check carefully)
• Cotton underwear (avoid lace with metal threads)
• Or no bra if comfortable (for shorter scans)

What to avoid:

• Underwire bras: The wire is metal—unsafe in MRI
• Bras with metal clasps: Most have metal hooks
• Lace with metallic threads: Some lace has metal

Tip: Wear a sports bra or a bra with a front plastic clasp. Or bring a bra to change into afterward.

Socks and Footwear

Socks:

• Wear socks—MRI rooms are cold
• Plain cotton socks are perfect
• Avoid socks with metallic threads (rare, but some do have them)

Shoes:

• You'll likely remove shoes anyway
• Wear slip-on shoes for easy removal
• Avoid shoes you have to lace/tie (metal eyelets)

Definitely Avoid

Surprising Sources of Metal

Some clothing has hidden metal:

• Decorative stitching: May contain metallic thread
• Graphic tees: Some inks have metallic particles
• Athletic wear: Some "performance" fabrics have metallic threads
• Shirts with foil or shimmer: Often contains metal

When in doubt: Bring a change of clothes or plan to change into a hospital gown.

Abdominal or Pelvic MRI

You may need to:

• Change into a hospital gown (common for abdominal/pelvic MRI)
• Remove pants and wear just the gown
• Wear a gown and keep your own top (if top has no metal)

Brain/Head MRI

You can usually wear:

• Your own clothes (if metal-free)
• But you'll remove:
  • All jewelry (including earrings, necklaces)
  • Hair accessories
  • Glasses (some have metal)
  • Hearing aids (may need to be removed)
  • Removable dental work (retainers, some bridges)

Extremity MRI (Arm, Leg, Knee, etc.)

You can often wear:

• Regular clothes (if no metal near the body part being imaged)
• But remove:
  • Jewelry from that limb
  • Watches, fitness trackers
  • Some clothing if it covers the area

You may need to change into a hospital gown if:

If you need a gown:

• You'll change in a private dressing room
• Your belongings go in a locker
• You can wear undergarments if they're metal-free (sports bra, cotton underwear)
• You'll get a sheet or blanket for warmth

Some tattoo inks contain metallic particles, especially:

• Older tattoos
• Certain colors (red, in particular)
• Tattoo styles with heavy shading

What happens:

• Most tattoos are fine
• Metallic ink can cause:
  • Warming or tingling at the tattoo site
  • Rarely, skin irritation

Tell the technologist if:

• You have a large tattoo
• You have a tattoo in the area being scanned
• You've had reactions during previous MRIs

Solutions:

• Cold compresses over the tattoo
• Monitoring during the scan
• Rarely, you might need a different imaging method

Temperature

• MRI rooms are cold—the machine needs to be cool
• Wear layers if possible (but check for metal)
• Bring socks
• You may be offered a blanket

Positioning

• You'll lie still for 30-60 minutes
• Wear comfortable, loose clothing
• Elastic waists are more comfortable than buttons/zippers
• Sweat-wicking fabric can help if you're warm-natured

Bathroom Access

• Use the restroom before your scan
• You'll be lying still for 30-60 minutes
• Plan ahead—you don't want to need the bathroom halfway through

Claustrophobia

If you're claustrophobic:

• Wear comfortable, non-restrictive clothing
• Layers can be comforting
• Bring a sweater or familiar item (if no metal)
• Ask about an "open" MRI option

Before You Leave Home

• Choose metal-free outfit (sweatpants + t-shirt + socks)
• Avoid underwire bra—wear sports bra or bra with plastic closure
• Remove all jewelry (leave at home)
• Remove hair accessories with metal
• Check for hidden metal in clothing
• Bring a sweatshirt if you tend to get cold (check for metal zippers)

At the Imaging Center

• Let staff know if you have any implants
• Tell them about any tattoos in the scan area
• Remove all metal (jewelry, phone, keys, coins)
• Ask if you need to change into a gown
• Use the restroom before the scan
• Ask for a blanket if you're cold

Pregnant Women

MRI without contrast is generally considered safe in pregnancy (after the first trimester):

• Wear loose, comfortable clothing
• No underwire bras
• You may need to change depending on the area being scanned
• Tell the technologist you're pregnant

Children

For children having MRI:

• Dress them in comfortable, metal-free clothes
• Sweatpants and t-shirt work well
• No zippers, buttons, or metal decorations
• Bring a favorite comfort item (if it has no metal)
• Some facilities allow a parent to stay in the room with the child (if parent has no metal implants)

People with Implanted Devices

If you have:

• Pacemaker or defibrillator: Usually cannot have MRI (some newer models are MRI-conditional)
• Metal implants: Most are fine, but tell the technologist
• Shrapnel or metal fragments: May need X-rays first to confirm location

Always tell the MRI staff about any implants.

1. "Should I wear my own clothes or change into a gown?"
2. "Are there any clothing restrictions for my specific scan?"
3. "Can I wear my jewelry if it's not near the scan area?"
4. "Is the room cold? Should I bring extra layers?"
5. "Can I use the restroom before the scan?"
6. "Will I need to change into a hospital gown?"
7. "Do I need to remove my wedding ring?"

What to wear for MRI: Simple, loose, comfortable clothing with no metal.

Perfect MRI outfit:

• Sweatpants or yoga pants with elastic waist (no zippers)
• Plain t-shirt (no graphics with metallic particles)
• Sports bra (no underwire)
• Socks (it's cold!)
• Slip-on shoes (you'll remove them anyway)

What to avoid:

• Jeans (zippers, rivets)
• Underwire bras
• Clothing with zippers, buttons, snaps
• Jewelry of any kind
• Hair accessories with metal
• Anything with embellishments that might contain metal

The safest approach: If you're unsure about any clothing item, leave it at home or bring a change of clothes. Changing into a hospital gown only takes a few minutes, and it guarantees you won't have to reschedule due to inappropriate clothing.

Remember: The goal is to get high-quality images safely and comfortably. Dressing metal-free helps you keep your own clothes, stay comfortable, and get through your MRI without delays.
