Diffusion tensor imaging (DTI) shows promise in the evaluation of white matter integrity, and may be useful in the evaluation of spinal cord function. The purpose of thise study is to determine normal values of fractional anisotropy, mean diffusivity and the three principle eigenvectors in various spinal cord regions, in a population of normal patients. The data obtained in normal patients may prove useful for comparison with pathologic states.
