【摘要】：[目的]研究多层螺旋CT (Multi-slice Spiral CT, MSCT)和多层面重建(Multiplanar Reconstruction, MPR)对颈椎椎间孔狭窄病变的价值,探讨神经根型颈椎病椎间孔狭窄的发生特点和原因。 [方法]研究对象为101例存在颈部神经根压迫症状、经MSCT薄层扫描和MPR重建证实的椎间孔狭窄患者,男性50例,女性51例,年龄31-68岁,平均47.5岁。MPR重建方式为矢状位、垂直于椎间孔走向的斜矢状位和平行于椎间盘水平的轴位重建,结合多方位重建图像综合分析颈椎间孔狭窄情况及导致狭窄的原因。 [结果](1)各年龄组中C5-C6椎间孔狭窄最常见(105/263,39.9%)。椎间孔狭窄以单节段为主(53/101,52.5%),三个节段和四个节段的椎间孔狭窄主要发生在50-59岁和60-69岁年龄组。(2)导致椎间孔狭窄的原因以钩椎关节骨质增生为主(114/263,43.3%),其次为两种狭窄因素共同引起(57/263,21.7%)。30-39岁和40-49岁年龄组中椎间孔狭窄主要由单一因素引起(90/105,85.7%),两种以上因素引起的椎间孔狭窄中有81.9%(68/83)发生在50-59和60-69岁年龄组。(3)椎间盘突出以中央型突出为主,占69.7%(161/231),后外侧型突出占30.3%(70/231)。导致椎间孔狭窄的椎间盘突出以后外侧型突出为主(63/75,84%)。 [结论]神经根型颈椎病椎间孔狭窄的原因以钩椎关节骨质增生为主,其次为两种因素共同引起。后外侧型椎间盘突出容易引起椎间孔狭窄。椎间孔狭窄节段数量及狭窄因素在不同年龄组间发生情况有差异。MSCT薄层扫描和MPR重建技术能够清晰显示颈椎间孔周围结构并能准确评价颈椎间孔病变情况。
[Abstract]:[objective] to study the value of multi-slice Spiral CT (MSCT) and multi-slice reconstruction (MPR) in cervical intervertebral foramen stenosis, and to explore the characteristics and causes of intervertebral foramen stenosis in cervical spondylopathy of nerve root type.[methods] A total of 101 patients with cervical nerve root compression, confirmed by MSCT thin slice scanning and MPR reconstruction, were enrolled in this study. 50 males and 51 females, aged 31-68 years, with an average of 47.5 years old, underwent sagittal reconstruction.The oblique sagittal position perpendicular to the intervertebral foramen and the axial reconstruction parallel to the intervertebral disc level were used to analyze the stenosis of the intervertebral foramen and the causes of the stenosis.[results] among all age groups, C5-C6 intervertebral foramen stenosis was the most common.It accounts for 69.7% 161 / 231, and the posterolateral herniation accounts for 30.3% of 70 / 231.The posterolateral herniation of intervertebral foramen, which resulted in stenosis of intervertebral foramen, was mainly 63 / 75 / 84.[conclusion] the main causes of intervertebral foramen stenosis in cervical spondylopathy of nerve root type are osteomatosis of hook vertebrae, followed by two factors.Posterolateral disc herniation is easy to cause intervertebral foramen stenosis.There were differences in the number of segments of intervertebral foramen stenosis and the occurrence of stenosis among different age groups. MSCT thin slice scanning and MPR reconstruction techniques could clearly display the periforaminal structure of cervical vertebrae and accurately evaluate the lesion of cervical interforaminal foramen.
