Result Time For Pet Scan. The norm is 5-10 days. I had a PET Scan done at 630 AM and was scheduled to see my Oncologist at 1000 AM.
As time went on the table slowly moved me through a tube. The entire PET scan process takes about two hours. The norm is 5-10 days.
The longer duration is because it includes the weekend.
The NCI recommends a low-carbohydrate diet for 24 hours before the PET scan. Despite my anxiety leading up to the scan I went the whole time without one cough. PET scan images can be combined with computed tomography CT images or magnetic resonance imaging MRI in a process called co-registration or image fusion. However 30 minutes is typically the average.
