I believe that these are all inflammation level SUV values. 2.5 is interesting, and is the beginning line for things that MIGHT be malignant, and should get someone's attention, 3.5-4.0 and up is a red flag to take a closer look via a biopsy or other sampling technique in most cases. With the utmost respect for Suzanne's comments, this is not an anatomical area that I would want to have a surgical procedure on without serious reasons. I would opt for a CT guided biopsy if the numbers were slightly higher just to be on the safe side and if that came up positive, then I would let the cutters have their way if everyone else on the team was on board with the idea. Please note the disclaimer that I am not an expert nor a doctor, and I only am passing on what 10 years of watching others deal with these things has taught me. Your milage may vary.
