Diffusion Tensor Imaging parameters have been shown to
be sensitive to changes in the diseased spinal cord
(SC). However, imaging the cord can be challenging due
to patient-related and physiological motion. Rapid
acquisition sequences such as Echo Planar Imaging (EPI)
are desirable but may suffer from image distortions.
Here we present a multi-centre comparison of two
acquisition protocols, one using ZOOM-EPI, and one only
using options available on standard clinical scanners
such as outer volume suppression (OVS).
