Voxel coordinates are in millimeters after transformation into standard Montreal Neurologic Institute (MNI) stereotactic space. Results have been corrected for multiple comparisons (p<0.05). PCA = Posterior Cortical Atrophy; AD = Alzheimer's disease; C = control; PCA versus AD = voxel showing greater atrophy in the PCA group than the AD group; AD versus PCA = voxel showing greater atrophy in the AD group than the PCA group.
