Maybe there should be a giant sign outside the room?

What about tattoos? Don't some have metal?

My wife gets regular MRIs. There is a 2 page questionnaire that goes through all sorts of things asking about medical patches, tattoos, different types of implants, metal fragments, and such. It’s reviewed line by line by the radiation tech before she is allowed anywhere near the MRI room.
