@vikkitennis I have had several MRIs since having my first SCS implanted in 2017. I tend to be cold blooded, so was never too warm in the MRI tube. But this is a potential issue with any SCS and perhaps some other medical devices. During my last MRI they refused to give me a blanket due to a policy change at the imaging center. Apparently, they had some patients get too warm due to metal medical devices, even if non-ferrous, and would no longer allow blankets for imaging patients with an implanted medical device.

I haven't heard of anyone having an MRI under anesthesia, but I know it's common for doctors to prescribe a Valium tablet for patients who experience anxiety in the MRI tube. Or perhaps imaging in an open MRI system would make the experience better for you.
