I saw a link to a CT scan, which I've seen, but not a PET scan...maybe I missed it?
Ah, my mistake. It must have been the PET scan I saw on TV, and Dr Crandal said one was done, my bad. I'm not aware of the other scan being anywhere on the net. I apologize for my confusion. The other scan I've seen a couple times on TV had black and white color (like a bone X-ray). In that one, the damage appeared to be more severe than the CT scan indicates.
