University of California, San Francisco 2012 Adult Human Magnetic Resonance Imaging Cognition Neuropsychological Test Aged Middle Aged Atrophy Pathology Physiopathology Brain Dementia Mental Disorders Frontotemporal Dementia Alzheimer's Disease UCSF Center for Imaging of Neurodegenerative Diseases 2002-2009 dataset 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.
