a CT, and an EEg displays more
functioninng abnormalites
vs CT/
MRI that show structural abnormalites. They also have
PET, SPECT, and fMRI which also display functioning., but not as common.
I'm not sure what they are specifically used for, I've been trying to find out for my own stuff, its very frustrating. I'm going to atleast insist on an EEg, so I have a test showing
brain functioninng as well as structure (CT). But, Probably and MRI too.
