Association between cervical MRI findings and patient-reported severity of headache in patients with persistent neck pain: a cross-sectional study

This study showed that, among patients with persistent neck pain referred to secondary care, degenerative MRI findings in the cervical spine were inversely associated with headache severity. The association between an aggregated score of MRI findings and headache severity was stronger than that of single findings. These findings reflect associations observed within a selected clinical population and warrant further investigation in populations with differing symptom profiles.
