In this work the results of a study investigating Cervical Spondylotic Myelopathy subjects using DTI are presented. We analyzed the FA as well as the parallel (LP) and radial (LR) eigenvalues of the diffusion tensor in stenotic and normal appearing regions of the cord. Diffusion Tensor eigenvalues were approximately constant along the spine, but with variations in regions with stenosis. FA was generally higher in the stenotic regions; however, LP and LR were generally reduced in regions of stenosis.
