I am stage 3 and my last scan was about 4 months ago and was clear. I will have my 12th and last dose of Opdivo this month. All my scans have been clear since my WLE/SLND January of 2019. My next scan is in a couple weeks. I called to asked and they said this was a head to mid thigh PET scan. The last one I had was whole body. I am wondering what other stage 3 (or stage 4) patients usually get. Whole body or skull to thigh? It seems my surgeon is more aggressive and he has been the one to order whole body scans but my oncologist seems to only order to thigh. Should I call and request whole body or is skull to mid thighs sufficient?
