X线片与螺旋CT对腰椎退变诊断价值的比较

Comparing Diagnostic Value of CT for Osteoarthritis of Lumbar Vertebrae With X-ray Plain Film

目的比较X线片与螺旋CT对腰椎退变的诊断价值。方法回顾性分析108例腰椎退变X线片与螺旋CT的影像学表现。结果在显示腰椎骨质增生方面两者具有统计学意义,即X线片优于CT。在显示椎间小关节退变方面两者的差异具有统计学意义,即X线片优于CT。在发现许莫氏结节方面CT与X线片比较其差异具有统计学意义,即CT优于X线片。在发现椎间隙变窄方面,X线片优于CT,椎间隙变窄与椎间盘突出关系密切,椎间隙变窄与椎间盘膨出关系不密切。结论腰椎X线片能发现并诊断腰椎退变;CT检查能发现X线片不能或不易显示的某些退变征象。当需了解椎间盘本身病变情况及周围软组织与神经改变时,行CT检查是必要的。

Objective To probe into diagnostic value of CT and X - ray plain film for osteoarthritis of lumbar vertebrae. Methods We analyzed signs on CT images and X - ray plain film images of 108 osteoarthritis of lumbar vertebrae. Results X - ray plain film was superior to CT in showing signs of hyperostosis , degeneration of intervertebral small joints and intervertebral space narrowing. CT was superior to X - ray plain film in showing Schmorl＇ s nodes. Intervertebral space narrowing was interrelated with disc protrusion. Conclusion Osteoarthritis of lumbar vertebrae can be diagnosed by CT scanning and X - ray plain film. Some signs of degeneration can be shown by CT, but X - ray plain film can＇ t. It is necessary to make CT scanning when we want to know pathological changes of disc and nerve.
