摘要： 目的 探讨MRI对新鲜与陈旧性椎体压缩性骨折的鉴别价值。 方法 回顾性分析43例胸、腰椎椎体压缩性骨折的MRI表现，MRI检查序列主要为T1WI、T2WI和STIR。 结果 本组43例共发现55处胸、腰椎椎体压缩性骨折，其中46处椎体被判定为新鲜骨折，T1WI呈低信号或低信号中混有少许高信号，T2WI呈高信号，STIR呈明显的高信号。9处椎体被判定为陈旧性骨折，在T1WI、T2WI、STIR与正常椎体信号一致。 结论 MRI能准确区分新鲜与陈旧性椎体压缩性骨折，在鉴定中有较高的价值。

Abstract: Objective To analyze and explore the value of MRI in distinguishing fresh from old vertebral compression fractures. Methods The features of MRI in 43 cases with compression fractures of thoracic or lumbar vertebral bodies were analyzed. MRI sequences included T1WI, T2WI and STIR. Results Fifty-five vertebral bodies in total were found compression fractures in 43 cases. Forty-six vertebral bodies, which showed low signals or low signals mixing a few high signals on T1WI, high signals on T2WI and significantly high signals on STIR, were identified as fresh compression fractures. Nine vertebral bodies were identified as old compression fractures, because they showed the same signals as normal vertebral bodies on T1WI, T2WI and STIR. Conclusion MRI could accurately distinguish fresh and old vertebral compression fractures, so it is valuable for the distinguishment in forensic identification.
