nonlinearly registered with QUARC, which estimates voxel-level deformation. Negative values are interpreted as shrinkage and positive values are interpreted as expansion. Deformation maps are projected onto the cortical surface in preparation for surface vertex-level GLM analysis. b) Preprocessed PET images are coregistered to the closest MRI to generate an SUVr image, and subsequently a "summary AV1451 score", c) Visualization of statistical analysis. At each vertex on the surface, Quarc deformation is regressed onto summary AV1451 score. In each plot, a point denotes an individual subject. Poster Presentations: Saturday, July 21, 2018 P101
