The actual tests took few minutes. For a scan, after injection, we were supposed to wait for half an hour. The wait-time turned out to be 1 hour after injection (1 hour before injection too for some reason) and the report said 20 minutes of wait time after injection. The staff and radiologists were professional and kind (Well, what else can they say except "wait for few minutes") and the tests per se were efficiently done. Just make sure you go right after a decent meal, since the wait time is easily 3+ hours for one scan and nobody will tell you why.
