Atleast in Long Island the clinics I've worked in are not in use much
of the time. With the exception of paper work you could probably get
same day appointments, I think they also reserve some emergency slots.

I have the impression that MRI would be better than CAT scan for this
purpose, but you'd probably want to ask a radioligist (sp?).

Let me guess you got hired to make anti drug ad's? Well maybe not if you
where you wouldn't bother with real experments, fake ones work just as well
and you don't have to deal with politically "invalid" results...
