Diffusion tensor images were acquired on the cervical spinal cord from C2 to C6 in four volunteers. Fiber tracking was done in the left and right lateral and dorsal columns and tract-specific fractional anisotropy, apparent diffusion coefficient (ADC) and magnetization transfer (MT) contrast were quantified per slice. The measures had left-right symmetry for both pathways. There was a small statistical difference in ADC between the lateral and dorsal columns.
