[QUOTE= Kiwi waiting to hear your take on it (and I was amused by this mistake in the U.S. NIH specs - ability to fly to Vancouver for PET scan - 10 plus hours, really!)[/QUOTE].

Thank you for the audio link Soccertese. It is very informative.

Listening to the Audio I see there was no mistake in the spec, trial participants did fly to Vancouver for a scan! Most humble apologies for my mistake. I live in the area so now to see if I can get on that trial!
