How To Prepare For A Pet Scan

How should I prepare for a PET scan?

The most common tracer used in PET is FDG. Therefore, I'm going to mention how you prepare for a FDG PET scan. For an FDG PET scan, the patient requires to fast for about 46 hours prior to coming to the clinic for their procedure. Also, we ask them to be well hydrated both before, during and after the PET scan. So basically these are the 2 major preparations that they need to do for FDG PET scan.
