This work provides preliminary diffusion tensor imaging
(DTI) results on an ex vivo porcine spinal cord on a
whole-body 7 Tesla. A readout-segmented echo-planar
imaging sequence using parallel imaging was optimized to
minimize magnetic susceptibility-induced image
distortions. As severe distortions occurred, an
additional post-processing correction tool was
subsequently run on two independent data sets acquired
with opposed phase-encode directions. Successful and
robust distortion corrections were observed along the
ten slices, leading the way to in vivo human spinal cord
DTI.
