Consenting patients referred for clinically indicated cervical spine MRI by their treating physicians to confirm cervical disc herniation will receive an additional MRI sequence, diffusion tensor imaging. This will provide a baseline. The DTI sequence will add five minutes to the procedure. Participants will return at 6 weeks for a follow up MRI of the cervical spine to include DTI and tractography. Participants will be asked to complete an anonymized questionnaire at enrollment and at follow up to provide information regarding their condition.
