“What should I do to prepare for a PET scan?”
I have to get a PET scan because I've been having a lot of migraines lately. Is there anything that I should do to prepare for one?

During a PET (positron emission tomography) scan, a trace amount of a radiolabeled glucose called 18-FDG (fluorodeoxyglucose) is injected into a vein. FDG is a type of sugar (glucose). Because cancer cells use glucose more quickly than normal healthy cells, cancer cells will uptake 18-FDG rapidly and gamma camera will be able to identify metabolically hyperactive malignant cells that are taking up injected FDG rapidly.
To prepare for PET scan you will be asked to follow limited carbohydrate diet for at least 24 h prior to scan, do not eat or drink anything, except clear water for 6 h before the scan. Routine medications may be taken, unless you have been instructed otherwise.

PET is overkill for migraines. Someone is making money off of you.
