Diffusion weighted imaging (DWI) of the spinal cord is complicated by strong susceptibility gradients as well as physiological motion. To reduce susceptibility effects and motion artifacts at the same time we present a single-shot spin echo EPI technique with a reduced field of view in the phase encoding direction. To avoid fold over a spatially selective signal profile and outer volume suppression are incorporated. The combination of these techniques enables high resolution DWI within all regions of the spinal cord.
