不同类型腰椎间盘突出症CT检查临床分析

Clinical analysis of CT in the diagnosis of different types of lumbar disc herniation

目的 探讨不同类型腰椎间盘突出症CT检查检出率及影像学征象.方法 对46例腰椎间盘突出症患者的CT检查影像学资料进行分析,比较CT检查检出率及影像学征象.结果 本组患者CT诊断椎间盘突出症阳性率为93.5％,出现腰椎间盘积气27例,腰椎间盘钙化24例,神经根受压18例,硬膜囊受压16例,Schmorl结节9例,椎间盘真空7例.结论 CT检查对于腰椎间盘突出症的诊断具有较高的检出率,能够满足临床检查的需求,可作为腰椎间盘突出症诊断的首选检查方法,但对游离型腰椎间盘突出症的漏检率较高,可结合其它检查方法共同诊断.

Objective To investigate the CT detection rate in the diagnosis of different types of lumbar disc herniation and compare the imaging findings. Methods Retrospective analysis of clinical data of 46 patients with lumbar disc herniation was conducted. Compare the CT detection rate and imaging findings. Results The positive rate of lumbar disc herniation diagnosed by CT was 93.5 ％, 27 cases of lumbar intervertebral disc pneumatosis, 24 cases of lumbar intervertebral disc calcification, 27 cases of root compression, 16 cases of dural sac compression, 9 cases of Schmorl's node, 7 cases of lumbar intervertebral disc vacuo. Conclusion CT examination has a higher detection rate for lumbar disc herniation, it can satisfy the needs of clinical examination, and can be seen as the preferred method for diagnosis, but it has higher loss detecting rate of free lumbar disc herniation, and can be combined with other methods of examination for the diagnosis.
