The 3D reconstructions of sample patients generated by the fusion of the automatically segmented FDG PET and CT data. Control subject (A) shows prevalent activity in the axial skeleton, whereas a patient treated with CBT (B) shows increased activity also in the hip bones and in the long bone shafts. (C) A patient treated with ACT shows a markedly increased glycolytic activity, extending up to the distal tibial epiphyses.
