An isotropic sub-millimeter spatial resolution can be achieved in diffusion MRI using advanced acquisition strategies and hardware at 7T. It is shown that an isotropic resolution of 1 mm results in micro-structural maps with more details, especially in the cortex, compared to 1.5 mm isotropic resolution. We show results based on diffusion acquisitions with 800 m isotropic resolution, showing fine structures even in basal regions of the brain, such as the Thalamus.
