MRI Dangers

I've been in an MRI machine many times before, so I could get pretty pictures of my brain and get paid for it. Oh, and help with the advancement of human knowledge and all that too.

So it was somewhat scary to come across this web page with pictures and stories of objects flying into the MRI. Since it's a giant magnet, any nearby metallic objects tend to fly at it with great speed. If a person had been in there when, say, the large floor buffer flew into the tube, they probably wouldn't live to see their brain's data in a science journal. Apparently there is also a danger of being eaten by a tiger while in an MRI.

I wonder what part of your brain lights up when you've been impaled by a sharp metal object?
