Objectives: To assess the ability of combined MR cortical structure volumetry and DTI to automatically detect regional brain changes in patients with Alzheimer disease (AD) and Frontotemporal dementia (FTD). Methods: 9 AD patients, 7 FTD patients and 7 controls were studied by 3D volumetric and DW MR imaging. An automated registration/segmentation pipeline defined cortical and subcortical regions of interest, yielding structure volumes and mean diffusivity. Results. Diffuse volume reductions and MD increases were found in both patient groups compared to controls. Conclusions: the protocol described has the potential to identify in vivo surrogate markers for brain pathologic changes in neurodegeneration.
