Why Can't You Wear Your Watch During an MRI?

What is an MRI?

MRI stands for Magnetic Resonance Imaging. It uses powerful magnets to look inside your body.

The Power of Magnets

MRI machines use incredibly strong magnetic fields, much stronger than ordinary magnets.

Metal Interference

Metal objects, like watches, can interfere with the magnetic field of the MRI machine.

What Happens to Metal?

Metal objects can move rapidly towards the magnet, which is why it’s crucial to remove them.

Safety Concerns

Metal can become a projectile when exposed to MRI magnets, posing a danger to everyone in the room.

Metals can distort the MRI images, making it hard for doctors to get a clear picture of your body.

Image Quality

Besides watches, items like jewelry, glasses, and even some clothing with metal threads must be removed.

Examples of Metal Objects

You’ll be asked to remove all metal items and change into a gown to ensure safety.
