Advantage of readout-segmented EPI in simultaneous multi-slice diffusion MRI measurements for identifying uncinate fasciculus

We evaluated the performance of diffusion MRI (dMRI) acquisition with simultaneous multi-
slice (SMS) readout-segmented echo-planar imaging (rs-EPI) in measuring the uncinate
fasciculus, which is typically affected by susceptibility-induced distortion or signal dropout.
We found that SMS rs-EPI data provides a larger number of streamlines supported by dMRI
data and larger fractional anisotropy in uncinate, as compared to conventional SMS single-
shot EPI data. However, such an advantage was not consistent across subjects in the …
