I am having my PET scan sometime next week, as soon as my insurance approves it. My Dr. did tell me about the possibility of false positives and false negatives. He also said that if the SUV value is 10 or greater they would probably look at taking out the nodes and having them checked. If it was a 2 or 3 they may wait a few more months and do another scan to see if they have grown or staying the same. I think your values are really high. I hope you get a Dr. to discuss these results with you before the 8th. that just seems like a long time to wait.
