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.
