摘要： 目的探讨螺旋CT重建技术对寰枢椎损伤的诊断价值。方法分析25例患者的螺旋CT重建图像,并与CT平扫、X线片比较。结果7例齿状突骨折中,X线显示4例,CT显示5例,CT重建确诊7例,且清楚显示骨折移位情况;6例X线、CT显示寰枢椎左右间隙不对称,通过CT重建排除寰枢关节半脱位;寰枢外侧关节脱位1例,CT重建可清楚显示,而X线片和CT平扫均未能显示;寰枢椎畸形3例,分别为齿状突、后弓缺如1例,齿状突发育不良2例,CT重建均能清楚显示,而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。结论螺旋CT重建技术能够提供准确、完整的影像学信息,在寰枢椎损伤与畸形的诊断中具有重要应用价值。

Abstract: Objective To evaluate diagnostic value of spiral CT reconstruction in atlantoaxial injuries.Methods The images of 25 cases of spiral CT reconstruction were analyzed and compared with images of CT scan and X-ray.Results In 7 cases of odontoid process fracture,X-ray demonstrated 4 cases and CT demonstrated 5 cases,whereas the spiral CT reconstruction diagnosed 7 cases,which could display the displacement of fracture clearly.The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases,while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation.There was one case of lateral atlantoaxial joint dislocation,which was demon-strated by the spiral CT reconstruction clearly but not by the X-ray and CT scan.There were 3 cases of atlantoaxial congenital deformity(1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process),which were displayed clearly by spiral CT re-construction,but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.Conclusion Spiral CT reconstruction can provide the most accurate and integrity imaging information and is very useful in the diagnosis of atlantoaxial injuries and deformity.
