Researchers seem nervous about the contrast dye used in the process. It would seem unwise to do a MRI with GBCA for fun or speculative purposes, on the other hand "makes 1 in a zillion people sick" is actually quite acceptable odds for something that's fatal unless treated. It seems those dyes can cross the blood-brain barrier as very few things can, which is good during the MRI process, however the body may or may not be terribly good at cleaning them out (and the process of cleaning those dyes out of the blood once they're outta yer brain is also hard on the kidneys). Also edited to add, we DO know everything there is to know about stupid tricks involving ferrous metal being attracted to giant MRI magnets with squishy humans in the way, and that risk of damage is probably higher than the GBCA risk.
