2、身的形态学变化。结果32例颈椎曲度变直,21例曲度呈反弓状,28例椎体不稳;5例骨性椎管狭窄,20例有椎间盘膨出,19例有椎间盘突出,9例后纵韧带增厚;发现椎动脉走行>3个弯曲23例,发现血管壁软斑块合并纤维斑块9例,软斑块、纤维斑块合并钙化斑块6例,单纯钙化斑块7例,椎动脉开窗畸形4例,横突孔异常者25例,骨质增生压迫椎动脉11例,椎动脉管腔轻度狭窄17例,中度狭窄12例,重度狭窄5例,血管闭塞2例;与临床诊断对比,20例符合神经根型颈椎病,19例符合脊髓型颈椎病,16例符合椎动脉型颈椎病,符合率分别为100%、95%、80%。结论颈部CTA可以二维、三维成像,清
3、晰地观察椎动脉和颈椎骨性结构、椎间盘、韧带、脊髓、神经根的多种异常征象,对神经根型颈椎病、脊髓型颈椎病、椎动脉型颈椎病的诊断很有价值。关键词:颈椎病;椎动脉;颈椎;椎间盘;血管成像;计算机体层成像DOI:10.3969/j.issn.1002-1671.2013.03.006中图分类号:R814.43;R681文献标志码:A文章编号:1002-1671(2013)03-0360-05DiagnosticvalueofjugularCTangiographyforcervicalspondylosisHEYong,LUXianzhi,ZENGYangdong(Depa
