Now that you bring that up, I wonder what would happen if a firearm just happen to get close to one while it was on?
.
Define "close". Rhetorical. When I enter from the hallway I have dentures, a wrist watch, folding pocket knife,
flashlight, a metal buckle on my belt, glasses, metal eyelets on my boots for the laces, and a wedding ring.
They let me keep the dentures (100% plastic) and the ring (100% not ferrous metal), but everything else
goes in a little locker. I strip down, they give me their disposable socks, boxers, and gown. Nothing else
gets within about 50-60 feet I'm guessing. Interesting question because their is nothing in the outer
hallway to advise people that there is an MRI machine nearby. The biggest concern is probably keeping
things out of the same room. The 2 professionals are right in the next room, must be some metal in
there with them, controls, computers, etc.
They have a LONG list of questions about whether or not you have any metal in or on your person. Piercings,
surgical, pacemaker, etc.
For the last one they even gave me an IV to inject a dye halfway through. I asked how are you going to do that
without metal. She smiled, said the IV needle was metal with a plastic sleeve. Once the IV was inserted the needle
was removed leaving only the plastic sleeve in my arm.
Over the years I've seen pics (no video) of what can happen when ferrous metal is in the room when that thing
is energized and it is not pretty. The MRI machine is a total loss. I have read but not seen what happens to
people + metal + MRI, and those descriptions are the stuff of nightmares. And I don't ever want to see it.
I very seriously doubt a firearm would discharge in such an event anymore than it would if dropped from a
height onto a solid surface. But the firearm and the MRI would probably both be destroyed.
