Cervical spondylosis can be detected by CT, and osteophytes and herniated discs, if any, can also reflect part of the cervical spondylosis. However, for cervical spondylosis, comprehensive examination or MRI is better, because CT cannot reflect the nerve compression. Usually, cervical spondylosis is the result of nerve compression, and the patient feels uncomfortable. MRI is more comprehensive at this time, and the nerve compression can be seen more clearly. If the cervical spine is not good, it is recommended to do an MRI first, but sometimes after the examination, it will be found that the cervical spine has more bony hyperplasia or the posterior longitudinal ligament is ossified. In the case of ossification of the posterior longitudinal ligament, CT examination is better, it can observe the bone better, and can clearly examine the severity of the ossification range of the posterior longitudinal ligament, so the two have their own characteristics, and cannot replace each other. It is recommended to do MRI first, and if more osteophytes are found after MRI, then CT examination is better and more comprehensive. In addition, a generalized X-ray can also reveal a lot of problems, so X-ray, CT, MRI, it is not possible to say which one is better, just that different tests have different characteristics. If you really want to reflect your condition comprehensively, it is best to have all three tests done, which in turn will give you a different perspective on your condition, as well as a more comprehensive understanding, which may also be more helpful for future treatment.
