Susceptibility related artifacts is one of the main problems in spinal cord DWMRI. We propose the use of Point Spread Function (PSF) mapping for retrospective correction of these artifacts in single shot diffusion weighted EPI of the human cervical spinal cord. Although further improvements are needed, this method enables the reduction of short scale artifacts around the intervertebral disks and proviedes better consistency of fiber tractography.
