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.
For a CT scan, you will lie on the examination table while it slowly moves through the center of the machine. The procedure is not painful but lying still on the table during the scan may be a little uncomfortable. The scan may take 15 minutes to 1 hour to complete, depending on the type of CT scanner being used and the size of the area being scanned.
