Surgical repair of the cervical spinal cord to correct instability induced through trauma or degenerative disease often precludes follow-up MRI due to severe artifacts caused by metal stabilization hardware. Postoperative imaging is essential to monitor the hardware positioning, disease progression and new complications that may occur after surgery. In this study, we investigate the imaging capabilities of the recently developed multi-spectral diffusion weighted PROPELLER technique within the spinal cord immediately adjacent to metallic instrumentation. In addition, we assess the quantitative stability of this approach relative to other conventional methods in cohort of normal controls.
