There is still a debate whether k-pace (high resolution) or q-space (high angular resolution) imaging is better to resolve crossing fibres. In the current study we use a recently introduced combination of zoomed imaging and parallel imaging to obtain diffusion-weighted images with isotropic high resolution and high angular resolution at ultra-high field strength. The acquired data with 1 mm isotropic resolution has sufficient SNR to resolve crossing fibres in the white matter.
