FIG. 3.

Common regions of glucose hypometabolism in patients with repetitive head impacts (RHI) and traumatic encephalopathy syndrome (TES). W-score frequency map showing common voxels with significantly low glucose metabolism (glucose uptake W score ≤ -2.0) on FDG-PET among five patients irrespective of underlying neuropathological diagnosis. Warmer colors represent voxels with a higher frequency of patients with low glucose metabolism (e.g., yellow and red voxels show regions where four or five patients had low glucose metabolism, respectively).
