Objective To probe into the features of CT imaging in cervical spondylosis and its diagnostic values.Method Clinical data and CT images of 206cases of patients with cervical spondylosis were analyzed retrospectively.Results There were 82cases of nerve root type

which in the CT were shown as increased vertical diameter of uncinate process with hyperosteogeny at the rear edge

hyperplasia of the front and rear parts of small joint axon and scoliosis of intervertebral disc.There were 62cases of spinal cord type

which in the CT were shown as hyperplasia at rear edge of the vertebral body

ossification of rear longitudinal ligament

narrow spinal canal

hypertrophy of subflavous ligament

hyperplasia at inner edge of intervertebral joint and bulgetype protrusion of the intervertebral disc.There were 35cases of arteriae vertebralis type

which in the CT were shown as increased horizontal diameter of uncinate process with hyperplasia at the lateral edge

narrow transverse foramen or direct compression of the arteriae vertebralis.There were 27cases of mixed type

of which the CT findings were the same as the above-mentioned types

no obvious characteristic manifestations were found.Conclusion CT examination can fully manifest the anatomical structure of cervical vertebral body and intervertenral space

range and degree of the hyperosteogeny

situation of the intervertebral disc and pathologic changes of the ligament

which provide reliable and accurate diagnostic basis for clinical classification.
