Single-shot
inner-field-of-view fast spin-echo imaging with MAVRIC is more robust close to metallic
implants than EPI and could be used for DWI of the spinal cord.
(a)
Localizer of a volunteer with metallic implants and
measured slice stack highlighted in orange. (b) 30 1x1x4mm³ transversal ZOOM
EPI acquisitions (c) 30 1x1x4mm³ transversal ZOOM MAVRIC FSE acquisitions with
a frequency increment of 500 Hz and 9 steps. The spinal cord is highlighted by
red dotted ellipsoids.
(a)
Localizer of water phantom with a diameter of 2.8 cm,
surrounded by 4 aluminum screws, with 2.9 cm and 3.3 cm to each other. (b) 7
out of 20 inner FOV FSE MAVRIC acquisitions with a resolution of
1x1x4mm³ (c) 7 out of 20 inner FOV FSE MAVRIC acquisitions with a resolution of
1x1x4mm³ and 81 MAVRIC frequency steps of Δω 500 Hz
