Official Title: Diffusion Tensor Imaging of the Brain and Cervical Spine: Evaluation of Reproducibility in Normal Subjects and Diagnostic Utility in Patients With Cervical Spondylotic Myelopathy
Brief Summary: More than half of the middle-aged population has radiologic evidence of cervical spondylosis (Irvine 1965) and a subset of this population develops cervical spondylotic myelopathy (CSM), a condition in which the spinal cord is impaired, either by direct mechanical compression or indirectly by arterial deprivation and/or venous stasis. In this study we aim to test the hypothesis that diffusion tensor imaging can provide prognostic information on the integrity of the spine in these patients which is unavailable from conventional MRI images
