Readout-segmented EPI (RS-EPI) has been shown as a promising candidate for reducing distortion in diffusion-weighted (DW)-EPI while being robust to motion-induced phase errors. However, the requirement of several adjacent segments (or 'blinds') in RS-EPI can make the scan time can prohibitively long particularly for thin slices which require a large number of slices to achieve full brain coverage. In this work, we reduce the minimum TR in RS-EPI with the use a simultaneous multislice acquisition using PINS multiband pulses coupled with blipped-controlled aliasing.
