A Technique for Dynamic Cervical Magnetic Resonance Imaging Applied to Cervical Spondylotic Myelopathy: A Reliability Study.

Study Design: Cross-sectional study.

Objective: To evaluate morphometric variations of the cervical spine in patients with cervical spondylotic myelopathy (CSM) using a standard technique of dynamic magnetic resonance imaging (MRI), to assess the inter- and intraobserver reliability of measurements of morphometric parameters based on this imaging, and to compare the resulting measurements with those previously published.

Summary Of Background Data: Because dynamic factors may contribute to the etiology and severity of CSM, dynamic (flexion-extension) MRI may be useful to better evaluate for spinal stenosis and cord compromise.
