Flori: Does this info below help? I read a few things and it appears it can be in your bodily fluids a few hours after?! I guess you shouldn't pee on yourself or your companion! I always take my mother and she sits with me. They only seemed concerned that we will talk which is a no, no.
Interesting, just one more damn thing to worry about, like we don't have enough. I will hope for good PET results for you. I'm having my noggin scanned on the 22nd and scanxiety has the best of me!
Patients who have PET scans do become radioactive for a short period of time. For most PET studies, radioactive material is injected into the patients an hour or two before the procedure. After patients have had the scan, they may still contain some of the radioactive material. The remaining radioactive material does not stay in them very long. Based on some information from a
National Council on Radiation Protection and Measurements Report (Report No. 124), if you're about three feet from the patient an hour after the PET scan, you receive 0.004 rad/hour. This means if you stood at three feet from the patient for one hour, you would receive 0.004 rad (a rad is a unit of radiation dose).
