The cerebellar cortical microstructure is important for several functions, like motor control, but remain largely underexplored in vivo due to its small thickness. Here, we combined a susceptibility-weighted acquisition with in-plane resolution of just 0.2x0.2mm2 at 7Tesla along with a fat-navigator-based prospective motion correction. Using this setup, the cerebellar layers could be seen in the phase images of all 4 MRI-naive participants. Our results show that the cerebellar layers can be consistently visualized opening new neuroscientific and clinical dimensions.
