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.
Itâs usually preferred that a person not eat for three or four hours before certain CT scans. Thereâs a small risk of nausea and vomiting during the scan, which may be reduced if the stomach is empty. An empty stomach might also improve some of the images collected. Check with your radiology center for specific instructions on how to prep for your CT scan.
