MRI/Magnet interaction
Yeah, so I've personally stuck my hand in an MRI without incident; however at the time I only had a V&P in that hand. Of I course I now have muliple M31s, but haven't been in the MIR room with them. I have a friend with an M31 who went into the MRI room today and states that it caused excrutiating pain. The site is also significantly swollen.
I would advise at the very least wrapping the finger or area tightly with a medical tape prior to having an MRI if possible. The bracing should be adequate to prevent any serious tissue damage. If I'm wrong... I'll let you know as soon as I get a chance.

Being that glass tags have iron components (not that I recommend it, but a neodymium magnet will stick to an implanted chip, and it did no harm to my xNT when I tried it), I wonder how they would react to an MRI, as well. I'm imagining the writable portions of their memory could be wiped/scrambled, especially by one of the higher power MRI machines, and I suppose the surrounding tissue could be stressed, though at a lower degree than by a magnet implant that was MRI'ed.
This has me thinking about the tattoo someone got and posted regarding magnet implants and a warning not to MRI. I've never had a tattoo, but maybe it wouldn't hurt to get something like that tattooed on. Something tasteful and informative. It's been said that one is unlikely to ever be placed in an MRI machine while unconscious, but, well, just in case. If I get MRI'ed with my implants, I want to be awake for it, damnit :)
Besides all possible issues to her body, we don't want to have the implant destroyed.
I told my doc everything about me including my implant on our first meeting.
I know this is an old post, but extra info never hurt anyone.
I just had an MRI of my head and shoulder. The machine was a 1.5 tesla and lasted about one and a half hours. As per other information in this post i wrapped my finger tightly before going in. This did little to nothing. Although my finger was wrapped tight i should have probably made it tighter, but worried about the length of the procedure been an issue.
There was enough pain to make me consider removing the magnet, if i need more MRIs. gripping it tightly with my other hand, did help reduce the pain. it's comparable to sticking your finger to a large neodymium magnet then pulling it off. At points the pain would decrease to the point i could nod off in the machine, or increase to the point of regretting the decision to get in at all.
All in all it was unpleasant but bearable. The tech was more interested than anything else, to the point of reading about it while i was in the machine.
I am not sure what the options for shielding are but i will absolutely be asking about it next time.
oh, additionally. No major issues after. it was tender and red for a couple of hours. no noticeable issues 24 hours later.
