Yeah, from what I have heard, given a random unknown metal, the odds are significantly greater that heating up is the concern rather than it being pulled out. Either one is a pretty bad day though.
Any day now we're going to see an advertisement where someone drinks water, dry instant noodles, and coins and walks to the MRI room (before being stopped to talk about some self cooking option)
I've forgot small copper coin in my pocket and gone to mri and I'll tell ya what) coin was HOT and slightly pulled so it fell off my pocket, i was scarily surprised because I've checked my pockets as I've been instructed and metal detector didn't singled either
