In this work three diffusion MRI protocol for the study
of the mouse spinal cord were compared. They are
different both in the number of directions of the
diffusion gradients and in the diffusion weightings
(b-values). The comparison was based on the variability
of the estimated diffusion parameters in both GM and WM
and on the detection of microstructural alterations,
highlighted by electron microscopy, in a murine model of
amyotrophic lateral sclerosis. The overall
best-performing protocol was the one with an
intermediate number of diffusion directions (12) and a
relatively high b-value (b=1200 s/mm

).
