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.
In addition, refrain from strenuous physical activity for 24 hours prior to your exam, such as working out, jogging, heavy lifting, etc. If possible, bring copies of your most recent CT, X-ray, or magnetic resonance imaging (MRI) films with you on the day of your PET/CT scan. Be prepared to stay at the imaging facility for approximately two to three hours. You will be asked to lie quietly for approximately 60 minutes before the scan, and to lie still for approximately 30 minutes while the scan is being performed.
