There are things they really don't make clear before you have an MRI, first of all that you need to be injected with imaging fluid - some sort of chemical that makes MRI work better; not a huge problem for me since I have plenty of experience giving blood - and secondly how bloody uncomfortable the things are. Not painful, just really confining, and you are lying on a completely flat surface and can't move at all, which by the time you're done guarantees that you will have backache. Oddly, it wasn't as claustrophobic as I expected because I could see out throughout the process - I presume because they didn't need to scan my head. I don't know how much difference that would make.
Fortunately I don't have any metal implants etc. which might have caused problems, it occurs to me that a lot of the cyberpunk tropes are REALLY incompatible with modern healthcare. All of those implanted sockets etc. would really not go well with multi-Tesla magnetic fields!
Anyway, that's something to cross off my bucket list, and without having to go through the biopsy etc. which would have been the next step if things had not been OK.
