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.
During the scan, patients will usually lie flat on their back while an X-ray tube rotates around the body, giving off an X-ray beam. CT scans are painless and take 10-30 minutes. They are usually performed on an outpatient basis, which means patients may go home on the same day.
