Interesting and a good review of Positron Emission Tomography as applicable to the brain.  However, being an American I had  to get my Australian accent filter out to understand the heavily accented Interviewer. ;)
I have had CTs, MRIs and Pet Scans during cancer diagnosis and treatment.

For the PET scan ...I was injected with radioactive  fluorine -18 solution ( I guess produced locally  in a cyclotron) with a  half-live of a couple of hours....  I was concerned... Gads; gammas rays shooting out of my body. I thought , well, it they are annihilating electrons in my body, then shouldn't I become positively charged?  ;D
Not cheap by the way, $ 8500 per pop. I believe it was coupled with CT, can't remember.

The physiological effects were interesting. I believe they told me not to get too close to people for  the day....Like no kissing, I guess....(and I tried not to pee on the grass  ;D )
It was interesting that I could feel the heat emanating from my body (somewhat aggravating) when I tried to get to sleep that night.

With God's grace I got through 6 weeks of radiation treatment and am completely cancer free today.
Interesting experience, but don't want to go through it again.
