FIG 3.

Voxel-level imaging findings in lvPPA and dementia of the Alzheimer type (DAT) compared with controls. 3D renderings show regions of reduced FDG metabolism and GM volume in lvPPA compared with controls and in DAT compared with controls. Note, lvPPA demonstrates hypometabolism and focal atrophy primarily in the left lateral temporal and inferior parietal lobes (including the left angular and supramarginal gyri) and left precuneus and left posterior cingulate gyrus.
