In this work multiplexed sensitivity encoding is combined with the continuous prospective motion correction of a segmented diffusion weighted acquisition to achieve high resolution DTI. The results show that prospective motion correction during DWI substantially improved image quality in the case of subject motion. In fact, our approach resulted in a considerable image quality improvement even without intentional subject motion. In conclusion, continuous prospective motion correction allows for high resolution multi-shot DWI both in the presence of substantial and also microscopic head motion.
