Back from PET scan. I got there a little before 11am. There were other people before me, so I wasn’t able to actually start the process until noon. At noon they gave me the PET scan injection, some kind of glucose-based radioactive isotope thing. Then I had to try to stay still for the next hour while it went through my system. The scan itself was very short (15-20min). Now (1:45pm) I’m back in my room with lunch on its way.
