predestination - previous determination as if by destiny or fate. doom, doomsday, end of the world, day of reckoning - an unpleasant or disastrous destiny; everyone was aware of the approaching doom but was helpless to avoid it; that's unfortunate but it isn't the end of the world.
That is 2 1/2 hours! Average is 3 hours now from start to finish. THEN we have to wait for the scan to be sent to the radiologist, and when he/she calls back, we can dispo the patient. I can't believe that every CT done in this country for a possible appy or whatever takes over 3 hours.
It could be anywhere from 1 to 2 hours, depending on which section of your abdomen/pelvis they are looking at. Also, if you are getting IV contrast check with the office to see how long you must not eat for before the scan. That way you wont have to reschedule due to being an NPO (stands for nothing by mouth) violator.est Answer: I am a CT Tech and the time it takes depends on a few things. The scan itself will take 30 seconds. Yes seconds not minutes like stated above.
