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.
1 Assuming that you are already inside the CT scanner ready to get scanned. CT scan without contrast (head, sinus, orbits, abdomen, pelvis, cervical, thoracic, lumbar and dental scans) take approximately 15 minutes. CT studies with contrast of the chest, pelvis, head or neck take approximately 30 minutes.
