目的 探讨三维CT(3DCT)在诊断颈椎病方面的价值。方法 采用 3DCT技术检查了 30 0例颈椎病患者。其中 ,神经根型 1 4 5例 ,椎动脉型 4 1例 ,脊髓型 4 0例 ,混合型73例 ,食管压迫型 1例。 3DCT观察颈椎病患者的颈椎骨质增生、椎间孔大小、椎动脉和颈椎骨质增生的关系、骨性椎管狭窄的改变。结果 2 1 .3%的患者有颈椎椎体骨质增生 ,4 2 .3%的钩突关节和 1 6 .2 %的小关节突柱有骨质增生 ,另外有1 2个小关节突有错位改变。在 1 4 5例神经根型颈椎病患者中 ,发现狭窄的椎间孔 4 38个。其中 ,C6 - 7和C5 - 6椎间孔狭窄占 81 .3%。椎间孔狭窄的原因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生Vu错位等。椎动脉型颈椎病表现为骨赘压迫椎动脉 (2 2 .0 % )和椎动脉变细或粗细不均 (6 5 .9% ) ,1 2 .1 %的患者未见异常。脊髓型颈椎病3DCT表现有颈椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。结论 3DCT能全面评价颈椎间盘退变及其产生的颈椎骨质增生对神经、血管和脊髓的影响 ,是一种诊断颈椎病的实用影像学检查方法
Objective To investigate the value of three-dimensional CT (3DCT) in the diagnosis of cervical spondylosis. Methods 30 cases of cervical spondylosis were examined by 3DCT technique. Among them, there were 115 nerve root types, 41 vertebral artery types, 40 spinal type, 73 mixed type and 1 esophageal compression type. 3DCT observation of patients with cervical spondylosis, foramen magnification, vertebral artery and cervical hyperosteogeny relationship, changes in bony spinal stenosis. RESULTS: Twenty-three percent of patients had osteoarthritis of the vertebral body, 42.3% of the uncinate process and 16.2% of the facet joint with osteo-hyperplasia. In addition, there were 12 minor articular processes Dislocation change. In 154 cases of radiculopathic cervical spondylosis patients, we found 4 38 narrow intervertebral foramen. Among them, C6 - 7 and C5 - 6 foraminal stenosis accounted for 81.3%. The causes of foraminal stenosis are osteophyte hyperplasia of the uncinate process, disc herniation, vertebral body hypertrophy, dislocation of the facet joint hyperosteogeny Vu and so on. Vertebral artery type cervical spondylosis showed osteophyte compression of vertebral artery (22.0%) and vertebral artery thinning or uneven thickness (65.9%), 12.1% of patients with no abnormalities. Myelopathy cervical spondylosis 3DCT manifestations of cervical stenosis, vertebral bone hyperplasia, posterior longitudinal ligament calcification, intervertebral space stenosis and cervical disc herniation. Conclusion 3DCT can fully evaluate the effect of degenerative cervical disc and cervical osteogenesis hyperplasia on nerves, blood vessels and spinal cord. It is a practical imaging diagnosis method for cervical spondylosis
