双排螺旋CT诊断骨梗死的临床价值探讨

Clinical value of double spiral CT in diagnosis of bone infarction

目的：探讨双排螺旋CT诊断骨梗死的临床应用价值。方法取自2011年6月～2013年6月间来本院就诊的10例骨梗死患者为研究对象，所有患者均经平片、CT检查，分析总结骨梗死的CT表现，评估CT检查诊断骨梗死的价值。结果 X线检查共发现病灶18处，8处定性诊断为骨梗死。 CT共发现病灶21处，13处定性骨梗死。 CT主要表现骨小梁稀疏破坏，髓腔内地图样改变，周围环硬化边；病变区范围大于X线平片。 CT对病灶的检出率及定性诊断率明显高于X线。结论双排螺旋CT在骨梗死的诊断上，其检出率及定性诊断率明显高于X线，有较高的临床价值。

Objective To investigate the clinical value of double spiral CT in diagnosis of bone infarc -tion.Methods Choosing 10 cases of bone infarction patients from June 2011 to June 2013 in our hospital, all patients were confirmed by plain film , CT examination , analyze and summarize the CT findings of bone infarc-tion, assessing CT examination diagnostic value of bone infarction .Results X-ray examination of 18 lesions were found, eight qualitative diagnosis of bone infarction .CT lesions were found in 21, 13 qualitative bone in-farction.CT mainly trabecular thinning destruction , marrow mainland patterns change around the ring hardened edge;lesions range greater than X-ray film.CT for lesion detection rate and qualitative diagnosis was signifi-cantly higher than the X-ray.Conclusion Double spiral CT has a significantly higher detection rate than X-ray in the diagnosis of bone infarction , and a high clinical value .
