随着CT检查技术的发展和颈椎椎间盘(以下称颈间盘)切割术的开展,颈间盘CT扫描已越来越普及。颈椎解剖结构复杂,生理弯曲大、椎间隙窄、椎旁附着诸多组织,又因颈部脂肪组织较少,易产生因气体与组织密度差异大引起的线状伪影。笔者采用GE公司生产的Synergy及Hispeed CT/i型螺旋CT扫描机进行 With the development of CT examination and the cervical disc (hereinafter referred to as intercostal disk) incision, cervical CT scan has become increasingly popular. Cervical spine anatomy complex, large physiological flexion, narrow intervertebral space, paravertebral attachment of many tissues, and because of the neck less adipose tissue, easy to produce due to large differences in gas and tissue density caused by linear artifacts.
