腰椎椎体后缘离断症的影像诊断(附19例分析)

Imaging Diagnosis of Lumbar Body Posterior Bony Edges Separation

目的 探讨腰椎椎体后缘离断症的影像诊断价值。方法 回顾性分析 19例经手术证实的腰椎椎体后缘离断症病例的影像表现。结果 19例X线平片显示腰椎椎体后缘离断症 11例 (5 6% ) ,行椎管造影 15例 ,显示腰椎椎体后缘离断症 11例 (73 % ) ,19例CT平扫显示 18例 (95 % )。结论 X线平片是检查腰椎椎体后缘离断症的基本方法 ,CT平扫是检查诊断腰椎椎体后缘离断症的最有效手段 。

Objective To investigate the value of imaging diagnosis for the lumbar body posterior bony edges separation. Methods Imaging findings of 19 cases of lumbar body posterior bony edges separation proved by operation were retrospectively analyzed. Results Eleven cases (56%) of lumbar body posterior bony edges separation were demonstrated by X ray, eleven cases (73%) by myelography, eighteen cases (95%) by CT plain scan. Conclusion X ray plain films was a primary method and plain CT scan was the most effective tool for detecting lumbar body posterior bony edges separation, while CTM could more accurately detect cramped degree of the vertebra tube.
