MAVRIC-SL is routinely used for clinical imaging close
to metallic orthopedic devices. MAVRIC-SL collects
multiple off-resonant 3D volumes acquired under a
constant slab selection gradient. The collection of
multiple 3D volumes presents challenges in maintaining
short scan times. Previous work has demonstrated how
hexagonal sampling can substantially reduce scan time
when employing 21 parallel imaging. In this work, we
demonstrate a variation of this method that allows
hexagonal sampling in conjunction with 32 parallel
imaging for more rapid imaging.
