核磁共振对骨质疏松性骨折疼痛责任椎体的诊断价值研究

Magnetic Resonance Imaging Diagnosis Value in Painful Vertebrae of Osteoporosis Vertebral Compression Fractures

目的探讨核磁共振（magnetic resonance imaging，MRJ）对骨质疏松性骨折疼痛责任椎体的诊断价值。方法回顾性分析135例骨质疏松性椎体压缩骨折患者的影像资料，分为单个椎体压缩组（A组）70例和椎体多节段压缩（2个节段以上）组（B组）65例，对两组患者的MRI资料及术前术后的疼痛视觉模拟评分（visual analogue scale，VAS）评分进行比较。结果A组70例患者70椎’皆为单一疼痛责任椎体，MRI的STIR（short tau inversion recovery）序列皆为高信号。B组MRI的STIR序列提示为高信号的椎体89椎，形态呈压缩性改变的62椎，形态无明显改变的27椎。两组患者间术前术后的VAS评分差异无统计学意义。结论MR的STIR序列可以有效确认骨质疏松性骨折疼痛责任椎体。

Objective To evaluate MR diagnosis value in painful vertebrae of osteoporosis vertebral compression fractures. Methods We performed a retrospective study of 135 patients with osteoporosis vertebral compression fractures. 70 patients with single vertebrae were classified as group A, and 65 patients with multi- vertebrae served as the group B. Pre and postoperative VAS score and MRI were assessed. Results 70 cases with single vertebrae served as painful vertebrae in group A. On MRI, the single vertebrae was found to be high signal intensity on short tau inversion recovery （STIR） sequences. In group B, eighty-nine vertebrae （62 compressive vertebrae and 27 intact vertebrae） were found to be high signal intensity on STIR sequences. No statistically significant difference was found in pre and postoperative VAS score between the two groups. Conclusion MRI with STIR sequences is an effective method to confirm painful vertebrae of osteoporosis vertebral compression fractures.
