@Roberta,
FWIW, I was scheduled and had 2 PET scans (at the VA hospital) so far in my journey back to health over these last 12 months. For the next one (11/14), I'm sending my pet, JellyBean, miniature French Poodle.
The difficult (torturous) thing for me was lying still for 25-30 mins on this unpadded board. My back cramps up sitting still under good circumstances...lying still like that requires me to do meditate in order to keep from screaming. The good thing is the results have been very good. It takes the Onco doc about 5 days to get results.
Whereas the bone marrow biopsy test (ugh and ouch), they send the sample off to one of the few labs in the country over on the left coast in Cal. Takes them about 10 days to give those results.
I'm hoping the best news possible for your health results.
