Is CT examination of cervical spondylosis effective?
Conclusion of CT examination of cervical spondylosis 1, 3? 4,4? 5 disc herniation 2, cervical hyperosteogeny Radiology four-dimensional film report only said that the cervical spine is smooth, the physiological curve is straight, and the neck is 4? 5, neck 5? 6, neck 6? 7. The intervertebral space is slightly narrowed, the posterior edge of vertebral body is hyperosteogeny, the uncinate joint is narrowed, and the anterior longitudinal ligament is calcified.
Orthopedic experts pointed out that CT has been used to diagnose vertebral arch insufficiency, hyperosteogeny, vertebral burst fracture, ossification of posterior longitudinal ligament, spinal canal stenosis, spinal canal enlargement or bone destruction caused by spinal cord tumor, and to estimate the degree of osteoporosis by measuring bone density. In addition, due to the cross-sectional image, the soft tissue and subarachnoid space inside and outside the epidural sheath can be clearly seen. Therefore, it is possible to correctly diagnose disc herniation and neurofibroma. Spinal cord or medullary cavity has certain value in the diagnosis and differential diagnosis of cervical spondylosis.
Clinical significance of CT examination of cervical spondylosis
1. Observation of congenital anomalies: CT can observe the structure of bones and soft tissues, and further clarify the congenital anomalies of the spine.
2. Identification of fracture and dislocation: CT can clearly show and accurately measure the degree of invasion of the lesion to the spinal canal and intervertebral space, and CT examination can accurately show the fracture of atlas.
Third, cervical disc herniation: CT can directly show the protruding nucleus pulposus and its degree of compression on dural sac and nerve root.
Cervical spinal stenosis: CT is a more accurate method to diagnose and locate spinal stenosis. You can measure the diameter and area of the spinal canal, observe its shape, understand its bones and soft tissues, and show the degree of compression in the spinal canal.
5. Exclude tumor and inflammation: If X-ray film confirms the lesion, CT can determine the lesion scope, vertebral body and its accessories, whether the lesion has invaded the spinal canal and intervertebral foramen, whether there is a mass near the vertebral body, and whether the lesion is invasive. CT can clearly show whether there is any bone abnormality.
Because CT can show bone diseases such as bone spur, ligament calcification and spinal canal stenosis more clearly than magnetic resonance, so in? X-ray plain film+MRI? When the above situation is unclear, applying for CT examination can further improve the accuracy of diagnosis.
