The feasibility to relate parameters derived from axial Diffusion Imaging of the cervical spinal cord to the vertebral level of the acquisition was investigated. Two slices were acquired at different levels of C3. The first slice was positioned where fibres of the ventral root were identified in the T1 weighted image, the second were no sprouting fibres were observed. Results suggest that the estimated diffusion parameters are sensitive to the position of the slice. A second scan of the same subject at a different time was able to reproduce the results of the first scan.
