Multiposition cervical MRI in the diagnosis of cervical spondylosis

Objective: To explore the value of multiposition cervical MRI in the diagnosis of cervical spondylosis. Methods: Totally 30 patients with cervical spondylosis diagnosed clinically underwent MR examination in neutral, hyperflexion and hyperextension positions. The differences of cervical disc herniation sagittal diameter index (SI) were compared among three positions. Results: In 30 patients, 92 intervertebral disc herniations were found. The differences of SI between the every two kinds of positions were statistically significant (all P<0.05). Moreover, the degree of intervertebral disc herniation was the most mild in the hyperflexion position and the most severe in the hyperextension position. Conclusion: The degree of cervical disc herniation is different in the different position MR cervical examination. Multiposition cervical MRI provides a new method for the pathogenesis study of cervical spondylosis, which contributes to the treatment of cervical spondylosis in clinic.
