AbstractThe protocol for spinal DTI nntl tractography with high SNR and spatial resolution has been developed arid tested on G healthy subjects and 1 CSM patient in a 3T system. Fiber bundlex were traced and were found running parallel to the cervical spinal cord correlating with the neuronal anatomy in normal subjects. The FA maps showed consistent low FA region connecting all spinal levels, which corresponded lo the grey matter structure in anatomical imaging, Spinal DTI in CSM showed diffusivity increase at compression sites. The proposed diffusion eigenvector-based method was able to differentiate between λa and λr even when there was a draxtic diffusivity change at compressed regions in CSM, which may facilitate better understanding of the pathophysiology of CSM. Our results indicated that using the current imaging and post-procensing protocols, spinal DTI can fm achieved with better grey white matter contrast, high inter-subject reproducibility and diagnostic ability. © 2006 IEEE.
