LOL, a doctor has to examine Terri before commenting on how MRIs work?
Well, I don't think that.
But I do think that the word of her guardian ad litems and court documents are more worthy of consideration than some guy who CLAIMS on the internet to be a doctor and see no reason why she can't have an MRI.
The next time you see YOUR doctor, ask him if you had electrodes in your head if you'd be able to get an MRI.
