The advent of slice accelerated imaging has allowed the
significant speedup of diffusion tensor imaging. Slice
accelerated imaging excels at accelerating imaging which
has a relatively long repetition time, such as readout
segmented imaging, which is inherently a dual-echo
imaging technique and typically has a repetition time of
over 100ms. This work demonstrates that the image
quality of diffusion tensor readout segmented imaging is
comparable to non-slice accelerated imaging, despite the
acquisition being at least 2 times faster.
