Metal in the Eye and MRI's
Has anybody had one of these orbital x-rays to determine if there are any
metal fragments in or around your eyes prior to an MRI? Apparently the magnet can move any small piece in your eye and do major damage. When I got to that point on the consent form I couldn't rule out the possibility....I guess I'll find out tomorrow. |

Yep, a few years back. Took about 1 minute - "stand here, hold this", click and it was done. They came back 5 minutes later and said no problems, go get your MRI, oh....be sure to remove any genital piercings as well. : ) |

I've found out that you can be safe wearing your genital piercings in an MRI if they're nonmagnetic (which of course most are) and it's not the area of the scan. http://answers.yahoo.com/question/in...8065648AA9OrhY Karl |

Damn, that has to be a powerful magnetic force. Metal does show up really well on xray. Outside of movement, induction heating seems to be part of the risk. I took a wire brush fragment to my eye once. Not something you forget about quickly.

Any metal in the body, if placed within the gradient coils and the RF coils, can get hot. No, make that HOT!!! They are pumping up to 14 KW of RF into your body in some of the newer machines. Jon |

Jon no, it depends upon the metal. i have a metal plate and screws in my neck and have had numerous mri's. yes, i've also had the orbital scan for eye metal fragments. you only need to do this once, and as long as you don't have any further eye/metal problems, it doesn't need to be repeated. |
