This data set was acquired with the aim of determining the structural and chemical changes that occur in the brain as a result of frontotemporal lobar degeneration (FTLD). The data includes proton density, T1, and T2-weighted neuroimages from subjects suffering from FTLD and Alzheimer's Disease, as well as a population of matched controls.

Data Acquisition Location: San Francisco VA Medical Center; Scanner Type: Siemens Vision 1.5T; Coronal T1 MPRAGE (orthogonal to long axis of hippocampus): TR=9ms, TE=4ms, TI=300ms, 1x1mm2, 1.5mm slice thickness; Coronal MPRAGE (orthogonal to PD, T2): TR=10ms, TE=7ms, TI=300ms, 1x1mm2, 1.4mm slice thickness; Axial double spin echo PD & T2: TR=2500ms, TE=20/80ms, 1x1.25mm2, 3mm slice thickness.
