Objective To explore the value and choice of X-ray, MRI and CT in diagnosing the nature of cervical spinal cord compressors.Methods From January 2014 to 2018,May 66 patients with cervical spondylotic myelopathy received surgical treatment in the second department of osteopathic surgery, the first affiliated hospital of xinxiang medical University. To analyze the diagnostic results and accuracy of X-ray, MRI and CT of preoperative patients for anterior cervical spinal cord compressors.Results According to the three imaging examinations and intraoperative confirmation, X-ray missed diagnosis rate was the highest, MRI misdiagnosis rate was the highest, some osteophytes and ossified posterior longitudinal ligament were misdiagnosed as herniated discs, and CT accuracy was the highest. Conclusion If there is high density shadow or unstable segment in the posterior edge of vertebral body or the back of intervertebral space on X-ray, MRI should be performed. If the lesion obviously involves the posterior of vertebral body or there is low or mixed signal on T1WI, further CT should be performed.
