A typical case of disagreement between observers. a is the baseline and b is follow-up. On the bottom, one of the foci with uptake on follow-up is presented. In general, all observers found that a decrease in FDG-uptake was seen on follow-up (b), but three observers found that new areas with high FDG-uptake represented new malignant lesions (PMD) and five observers evaluated PMR, indicating the foci most likely to be benign. All observers reported a 51 % SULpeak decrease
