What are the examination methods for vertebral artery type cervical spondylosis?

The main diagnostic methods for vertebral artery type cervical spondylosis include the following: 1. Cervical spine X-ray: Assesses cervical curvature and bone spurs to determine the presence of cervical spine abnormalities. 2. Cervical MRI: Uses magnetic resonance imaging to evaluate the cervical spine for pathological changes such as intervertebral disc herniation or spinal canal stenosis. 3. Vertebral angiography: Involves injecting contrast agent and using computed tomography to obtain images that directly show the vertebral artery and its branches. 4. Transcranial Doppler ultrasound: Measures peak blood flow velocity in the vertebral artery to detect abnormalities. 5. CT angiography: Provides a clear visualization of the vertebral artery and its branches, playing an important role in diagnosis. The appropriate examination method should be selected based on the patient's specific clinical condition.
