Flexion/Extension Cervical Magnetic Resonance Imaging: A Potentially Useful Tool for Decision-Making in Patients with Symptomatic Degenerative Cervical Spine.

Objective: To evaluate the reliability and usefulness of cervical flexion/extension magnetic resonance imaging (MRI) as a tool for decision-making regarding treatment of symptomatic cervical spondylosis.

Methods: We prospectively collected demographic, clinical, and flexion/neutral/extension MRI data for consecutive 24 patients who had presented with symptomatic cervical degenerative disease. From the survey responses, we analyzed the agreement between clinical interpretation and judgment when neutral MRI (nMRI) versus flexion/extension MRI (fMRI/eMRI) had been provided.
