Ultra-high field MRI combined with strong gradients gives access to ex-vivo anatomical and diffusion MRI datasets at the mesoscopic scale. This wok presents the unique CHENONCEAU dataset acquired on an entire left hemisphere (and soon on an entire brain) at 11.7T with ultra-high resolutions (100, 150, 200µm) thus paving the way to the creation of a novel mesoscopic MRI atlas of the human brain structure, connectivity and cytoarchitecture.
