A and B are mean (with range in parentheses) for 18F-FDG SUVmax and SULpeak uptake values and change in uptake for 28 patients completing 2 18F-FDG PET scans. C is mean (with range in parentheses) for 18F-NaF SUVmax values and change in uptake for 24 patients completing 2 18F-NaF PET and 2 18F-FDG PET scans.
