The rotating single-shot acquisition (RoSA) technique is proposed to accelerate multi-shot diffusion imaging acquisitions by acquiring one shot per diffusion direction. The RoSA approach utilizes similarity existing in diffusion-weighted contrast for image reconstruction. It has been successfully implemented with echo planar imaging (EPI). In this study, we use the RoSA approach to improve turbo spin-echo (TSE) based multi-shot sequences. In particular, we will demonstrate that with the same acquisition time, RoSA increases the diffusion angular sampling resolution by 3-fold compared to a Turboprop sequence.
