Not mentioned: the following suicides of the MRI technicians.

I just had an MRI on my knee a couple of months ago. I was smart enough to leave my glasses in another room.

Also, holy crap are those things loud. Every time you see a scene on TV, say, where House is calling Foreman a spade in the MRI room, it's total bullshit. They gave me industrial ear protection and I couldn't hear anything else.

Not to mention that ridiculous scene where House did an MRI on the guy who was holding a gun. Sure, he moved the gun away from the MRI, but not by all that much, and only because it was interfering with the MRI's readings.

House is total bullshit anyway. He walks into operating rooms with no mask on. "Let me just breathe my germs into your open wound." Half the stuff he does wouldn't fly in any hospital or it'd get shut down. But it's like most television and movies - they have to see the actor's faces and they want to make things seem dramatic. (Along a similar vein - anything in movies or t.v. with firefighting where you see some firefighter's face while they're in a burning building putting a fire out, is bunk. They're supposed to wear hoods that cover everything but the eyes.)

I had to have an MRI of my head. I layed there without enough space between my nose and the machine to put my hand between them. I had to keep my eyes shut so I didn't think about what would happen if the MRI collapsed and crushed me. I also found out that an MRI takes a long, long time. Mine took somewhere between 30 minutes and an hour.

No, but I saw a cat at the vet that did!

Extra stars for piquing my interest, sir. Even without solid metal, how many Tesla would be needed to rip the very iron out of my blood, for example?

One. And he wouldn't need a magnet.

Mythbusters debunked the tattoo myth, but anyone wearing piercings who tries to get an MRI won't be wearing those piercings for very long. They keep a carbon fiber winch around to remove metal objects without going having to go through the 12 hour power-up cycle

I have never seen any implant made of steel. Everything, from clips to artificial valves to stents to joints, are made of titanium, which is lighter and stronger and is MRI-safe.
