Coronal and axial slice of the average cortical F-18 MK-6240 SUVR [standard uptake value ratio] image for each study population. SUVR images were corrected for partial volume effects and masked with the gray matter mask used for volume of interest delineation. Overall tau accumulation is comparable between the late-life depression (LLD, middle column) and non-depressed cognitively unimpaired comparison (HC, left column) groups, while abnormal tau accumulation, which is most pronounced in the mesial temporal lobe, can be seen in the mild cognitive impairment due to Alzheimer's disease group (right column).

Example of the flortaucipir tau-PET signal and distribution of low grey matter volume in a single former athlete. Spatial maps of the flortaucipir tau-PET standardized update value (SUVR) (top) and the reduced grey matter volumes showed in blue and defined as voxels with a w-score of >1.5 below the mean (bottom) in a single former athlete.
