I'd been inside the PET ring before, so that was no big deal, but I'd forgotten about the line in my arm through which they put some radioactive dye. I was asked to lie still and not to read or use my cellphone to access the internet, so that it would be taken up by the brain without ... I suppose ... favoring the part that likes reading or looking at pictures of cats.
Afterwards, they gave me a card saying I'd been injected with a radioactive tracer, in case I went into an airport or a federal building or something else where I might be scanned for radioactives. It could have been kind of embarrassing, but at least I got some superpowers out of it!
