Ah yes, PET Scans. I have had one. It takes an awesome picture, but is horribly boring and dreadfully uncomfortable. I had one so they could see what was happening during a migraine. Not overly fun at the time and just confirmed what the MRIs and CT Scans showed. I do hope you get more answers from yours.
