螺旋CT三维重建对颈椎病诊断的应用价值

Value of three-dimension spiral CT reconstruction in diagnosis of cervical opondylosis

目的探讨螺旋CT三维重建在颈椎病诊断中的应用价值。方法对135例颈椎病患者进行螺旋CT薄层扫描,而后对图像进行3D和MPR处理,观察颈椎椎体骨质有无改变,椎间孔的大小,小关节突的改变及椎动脉受压的情况。结果笔者发现有95例有骨质增生,椎间孔狭窄,钩突关节等小关节增生变形,有15例有椎间盘突出,有23例椎管狭窄,韧带钙化,椎间隙狭窄等,有2例见有食管压迫征。结论多排螺旋CT的三维重建对颈椎椎体的骨质改变,对钩突关节等小关节及椎间孔的增生狭窄,以及椎体与周围软组织的关系均能直接观察到,因此对颈椎病的诊断多排螺旋CT的三维重建是准确的影像学检查手段。

objective To investigate the value of three-dimension spiral CT reformation in diagnosis of cervical spondylosis. Methods Multiplanar reformation （MPR）and three-dimension（3D）reeonstmction were performed in 135 patients with cervical spondylosis after thin collimation siral CT scanning.The change of bone and UVJ, the size of intervetbral foramen and the compression of cervical artery were assessed. Results Osteophytasis,intervetbral foraminal stenosis and distortion and hypertrophy of UVJ was found in 95patients.Tbere were 19 cases of intervertebral disk herniation,23cases of opinal tube stenosis and ligamental calcification and intervertebral space stenosis ,and 2cases with compression of esophagus. Conclusions 3D reconstruction of spiral CT can show hypertrophy of vertrebral body and UVJ, stenosis of intervertebral foramen and relationship of surround soft tissues directly .It＇s a efficient modality for diagnosis of cervical spondylosis.
