Q. for Dr. Z. or anyone else who may have the necessary expertise:
Is there any way for a subject to use a cell phone while
undergoing a cranial MRI? For that matter, is there any type or
frequency of EM radiation that a cell phone produces which is more
powerful than that which would be experienced by a person
undergoing a MRI of his/her brain? If not, how could any effects
be definitively attributed to the cell phone radiation?
well - your cell phone would immediately be sucked up against the
magnet unless you held on tight. I am not sure if it could work at
all (mine sure doesn't when I am in the MR suite). If it did work
it would probably mess with the MR signal which is after all a
radiofrequency signal.
That was what I thought, but it is nice to have it confirmed by an
expert.
My experience with MRIs comes mostly from having my head examined,
but I'm pretty sure that the room is a Faraday cage to contain the
substantial RF output, so it would be just about impossible to make a
cell phone work in there. You'd probably have to build a cell inside
the room (or use a simulator, as seen on "Myth Busters").
At the hospital where I work the MRI is indeed inside metal walls,
which had the result that pages were not received on the floor below
the MRI room.
