Cervical headache is a headache symptom caused by cervical spondylosis, which can usually be found out by doing cervical spine X-ray, cervical CT, MRI and other tests. 1. Cervical spine X-ray: Through cervical spine X-ray, you can see the changes of the physiological curvature of the entire cervical spine and whether there is cervical spine hyperplasia. It can initially determine the headache caused by cervical spondylosis, and at the same time, it can exclude tumors, infections and deformities of the cervical spine. 2. Cervical CT: Cervical CT examination is mainly a coronal plane scan of the neck, which can see disc herniation, vertebral degeneration, osteophytes, spinal cord and nerve root compression in the spinal canal. Therefore, patients with symptoms of headache caused by cervical spondylosis can also be detected by CT of the neck. 3. Magnetic resonance: Magnetic resonance is a necessary examination method to diagnose headache caused by cervical spondylosis. Cervical MRI can clearly show cervical disc herniation and cervical stenosis, so most cervical spondylosis and cervical disc herniation can be determined by cervical MRI. It is recommended that patients with cervical spine headache should go to the neurology department of regular hospitals in time and choose the suitable examination method under the guidance of doctors.
