多体位颈椎MRI诊断颈椎病

目的 探讨多体位颈椎MRI对颈椎病的诊断价值。方法 对30例临床诊断为颈椎病的患者进行颈椎中立位、过屈位、过伸位MR检查,比较三种体位下颈椎椎间盘突出矢状径指数(SI)的差异。结果 30例中共发现颈椎椎间盘突出92个,两两组间比较,三种体位下SI差异均有统计学意义(P<0.05);过屈位椎间盘突出程度最轻,过伸位椎间盘突出程度最重。结论 不同体位下颈椎MR检查显示椎间盘突出程度有所差异。多体位颈椎MRI对于临床选择颈椎病治疗方案有着重要意义,也为研究颈椎病发病机制提供了新的方法。

Multiposition cervical MRI in the diagnosis of cervical spondylosis

Objective To explore the value of multiposition cervical MRI in the diagnosis of cervical spondylosis. Methods Totally 30 patients with cervical spondylosis diagnosed clinically underwent MR examination in neutral, hyperflexion and hyperextension positions. The differences of cervical disc herniation sagittal diameter index (SI) were compared among three positions. Results In 30 patients, 92 intervertebral disc herniations were found. The differences of SI between the every two kinds of positions were statistically significant (all P<0.05). Moreover, the degree of intervertebral disc herniation was the most mild in the hyperflexion position and the most severe in the hyperextension position. Conclusion The degree of cervical disc herniation is different in the different position MR cervical examination. Multiposition cervical MRI provides a new method for the pathogenesis study of cervical spondylosis, which contributes to the treatment of cervical spondylosis in clinic.
