Cervical MRI can find out the following: First, cervical disc herniation and cervical spinal stenosis: cervical MRI can clearly show cervical disc herniation and cervical spinal stenosis, so most cervical spondylosis and cervical disc herniation can be judged by cervical MRI. Second, cervical spinal cord injury: cervical MRI can clearly show the neuropathy of the cervical spinal cord, such as ischemia, hypoxia, necrosis, and even softening, which can be directly judged on MRI. Therefore, MRI is usually recommended for patients with cervical spine disease, and not CT examination. MRI can clearly show most cervical spine lesions, while CT can only show cross-sectional or single-level examinations, which are not as clear as MRI.
