Diffusion-weighted, readout-segmented echo-planar imaging is a technique that can produce higher resolution diffusion images than conventional single-shot approaches but is very slow. We accelerated it using simultaneous multislice methods and by using partial Fourier in the segmentation dimension. Results are shown with 133 whole-brain volumes of 1 mm isotropic, acquired in 45 minutes.
