Cervical plain scan plus enhanced CT can detect diseases of the cervical spine, cervical intervertebral discs and soft tissues of the neck, and can see cervical masses and space-occupying lesions more clearly. 1. Problems of the bony structure of the cervical spine: such as cervical fractures, cervical spondylolisthesis, cervical osteophytes, cervical foraminal stenosis, etc., as well as changes in the shape of the spine such as scoliosis. It is possible to determine whether the nerves are severely compressed by observing the bony proliferation in the posterior part of the intervertebral space, as well as the specific situation of cervical fracture caused by trauma, which is a guide for surgical treatment. 2. Degeneration of cervical intervertebral discs: such as cervical disc herniation, bulging, and cervical spinal stenosis, and calcification of ligaments such as the posterior longitudinal ligament can also be seen. 3. Cervical soft tissue lesions: such as goiter and cervical vascular lesions. Enhanced CT provides a clearer view of masses such as goiter and space-occupying lesions such as malignant tumors. Understanding the relationship between the mass and the surrounding blood vessels, as well as the invasion of the surrounding blood vessels, can help to formulate a surgical plan. Neck scanning plus enhancement CT needs to be chosen by the doctor according to the needs of the diagnosis of the disease.
