High angular resolution diffusion imaging is a useful
tool in exploring cerebral microstructure, but long scan
times and geometric distortions have impeded its
translation to clinical practice. In the present work, a
strategy integrating advantages from accelerated
multishot diffusion imaging, multiplexed sensitivity
encoding and compressed sensing is proposed to provide
reductions in scan time and in geometric distortions.
Four-fold improvements in distortion level and as much
as three-fold reductions in scan time were achieved for
HARDI acquisitions.
