MR骨髓异常信号对椎体外伤压缩性骨折的诊断意义

The MR Diagnostic Significance of Bone Marrow Abnormal Signal in Traumatic Traumatic Compression Frature of Spine

目的:分析探讨骨髓异常信号对椎体外伤压缩性骨折的诊断意义。材料与方法:收集20例椎体外伤压缩性骨折和15例椎体退行性变扁的MR资料进行回顾性分析阅片,分别观察并统计两组病变椎体内出现的长T1、长T2骨髓异常信号影的多少,并对结果进行t检验。结果:发现压缩性骨折比退行性变,椎体内更多地出现骨髓异常信号(P<0.01)。结论:骨髓异常信号是诊断椎体外伤压缩性骨折的一个重要证据,应予充分重视。

Purpose： To analyse MR diagnostic significance of bone marrow abnormal signal in traumatic compression frature of spine. Materials and Methods： The MR imagines of two groups of flattening veterberal bodys were analysed retro- spectivly in this article. Group 1 （20 cases） were caused by trauma, Group 2（ 15 cases）were caused by retrogression. Au- thor viewed the abnormal findings of bone marrow signal of the vertebral bodys （hypointense on T~ WI, hyperintense on Z2 WI） in the two groups. The frequenc of the two groups of abnormalities were recorded and done statistical treatment. Results： The frequenc of abnormalities were signfically different between Group 1 and Group 2 （ P 〈 0. 01 ）. Conclusion ： The bone marrow abnormal signal is a important evidence for traumatic vertebral compression fracture, so it should be paid attention to at the time of diagnosis.
