MAPT and Dravet syndrome: Visual inspection of the [18F]-AV1451 at T4 revealed two main observations: (i) a stereotypical pattern of elevated tau deposition, characterized by predominant binding in the bilateral precuneus and temporoparietal cortices (Fig. 1) and (ii) in contrast to the often-reported striatal pattern of [11C]-PiB signal in DS, this region was relatively spared of [18F]-AV1451 binding (Fig. 1).
