What will I experience during a PET scan?
There may be a small sensation of pain when the needle enters the skin at the time of trace administration to the vein, but other than that a patient doesn't really feel any different before, during or after the Positron Emission Tomography (PET) Scan. When they lie down in the bed of a PET Scanner basically they just relax. They should not move or talk during that time but there is really no specific sensation or pain of any sort during that procedure and the PET Scan by itself doesn't do anything to the patient. So it's a very relaxing or actually a very safe procedure to do.
