Permitted piercing material during an MRI examination

What piercing materials are permitted during an MRI examination?

During an MRI scan, strong magnetic fields are applied to the body. Therefore, non-magnetic materials must be worn. The following are considered particularly suitable:

• Titanium (G23 / ASTM F-136)
  Non-magnetic, highly compatible, and considered very safe.

• Plastic (Bioflex / Bioplast)
  Completely metal-free and therefore ideal for MRI examinations.

• Glass, wood, or stone
  Non-magnetic, provided there are no metal components or coatings.

NOT suitable are:

• Surgical steel (contains iron and may be magnetic)
• Gold-plated materials (base material often magnetic)
• Unknown metal alloys
• Jewelry with moving metal parts or magnetic clasps

These materials can:

• be attracted by the magnetic field
• heat up
• cause image distortion

Important to know

If in doubt, remove jewelry before the MRI examination or consult with medical staff.

Anyone who requires regular medical examinations should have suitable plastic or titanium replacement jewelry available for such cases.
