Comparing Brain Images Before and After MRI-upgrade - TimFit Upgrade Study

Brain imaging using magnetic resonance imaging, using several MRI sequences: structural imaging (grey matter, using T1-imaging), cerebral perfusion using arterial spin labeling), functional and effective connectivity (using resting-state functional MRI), white matter tracts (using diffusion imaging), white matter lesions (using Fluid-attenuated inversion recovery MRI (FLAIR)) and microbleeds (using Susceptibility weighted imaging (SWI))
