Get copies of all of your imaging studies, I know from professional experience that it can be a pain in the ass sometimes to get copies after the fact. Plus, it's getting easier to do a 3D print of MRI studies. If they do an MRI of your brain ask for a CD of the study in DICOM format, that's what you'll need. I saw on Reddit that someone made a lamp of their brain. Edit - Hope all goes well for you.
