Obviously I have no first-hand experience with implanted magnets, but MRI magnets are generally getting stronger. What is safe for a 1.5 tesla MRI may not hold for a 3-4 tesla MRI. The rapid magnetic oscillation has been known to heat up wires and cause burns.
There's some people horsing around with 4T MRI that might give you pause.

- onemoreact 15y agoThanks for that, I suspect infection is still probably a more serious risk overall, but a 4+T MRI does give me pause. PS: Then again at 10T you get to fly so it may still be worth the risk. http://www.youtube.com/watch?v=A1vyB-O5i6E http://www.youtube.com/watch?v=A1vyB-O5i6E ;-)
