The Big Magnet!
An MRI is like a giant magnet. It helps doctors see your bones and muscles without any ouchies.
Many people love painting their nails with colorful, sparkly polish!
Some nail polishes have tiny bits of metal to make them shiny.
The MRI's magnet can react with metal, which can sometimes cause problems.
Doctors might ask you to remove your polish so the MRI pictures are clear and safe.
Not all nail polish needs to be removed. It depends on what's in the polish!
If you're unsure, look at the nail polish bottle or ask an adult.
Always a good idea to ask your doctor if you need to remove your polish before your MRI.
