We propose a non-Cartesian high resolution reconstruction of diffusion-weighted magnetic resonance imaging (DW-MRI) using multi-snapshots acquired with rotated K-spaces. Our technique boosts the signal level by reducing the echo time and by increasing voxel size for each snapshot. The final high resolution image is reconstructed by fusion of the snapshots, which were corrected for Echo-Planar-Imaging (EPI) distortions. We applied and evaluated different EPI correction methods. Through qualitative and quantitative evaluations based on in-vivo experiments, we showed that our protocol and image reconstruction technique leads to high spatial resolution and high signal-to-noise ratio DW-MRI.
