摘要
目的 探讨三维CT对神经根型颈椎病的影像学诊断价值。方法 采用体积重建、最大密度投影和曲面重建方式进行重建 ,显示方法 :采用椎间孔内口、外口、轴位显示及斜位重建 ,观察颈椎骨质增生及神经根走行情况。结果 12 8例神经根型颈椎病患者中发现狭窄的椎间孔 4 2 1个 ,其中81 3%位于C5～ 6、C6～ 7。椎间孔狭窄的原因包括钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生或错位。结论 三维CT能立体多角度地展现椎间孔的形状及其相邻结构的解剖关系 ,能较容易地断定病变的程度和范围 。
Objective To evaluate the imaginological diagnosis of radicular type cervical spondylosis with 3D CT. Methods The reconstructed method contained volumetric redering(VR), maximum intensity projection (MIP) and curved planar reconstruction (CPR). The display methods include: ①cervical osteophytosis observation; ② external, internal display and axial foramina as well as oblique reconstruction; ③nerve root display. Results Among 128 cases with radicular type spondylosis, there were 421 intervertebral foraminal (IVF) stenosis, 81 3% of which located in C 5～6 and C 6～7 . The causes of stenosis IVF include UVJ osteophytosis, intervertebral disk herniation, vertebral hypertrophy, FJM osteophytosis/dislocation. Conclusion 3D CT can fully display intervertebral foraminal form and its relation with adjacent structure and easily evaluate degree and range of lesion. 3D CT is one of the practical radiological methods for the diagnosis of cervical spondylosis.
