磁共振在评估腰椎椎体间融合术后骨性融合中的价值(1)
【摘要】 目的：探討磁共振技术在评估腰椎椎体间融合术后骨性融合的临床价值。方法：回顾性分析2012年1月-2014年6月本院收治的36例因腰椎退行性病变行腰椎椎体间植骨融合术(transforaminal lumbar interbody fusion，TLIF)患者的临床资料，收集所有患者随访2年内的X线、CT、MRI影像学资料，分析术后3个月、6个月、1年、2年不同影像学检查手段在评估椎体间融合状态的效果。结果：术后3个月、6个月、1年、2年腰椎X线、CT扫描重建、MRI所示椎间融合率为16.67%、8.33%、0，80.56%、61.11%、55.56%，97.22%、83.33%、86.11%，100%、97.22%、97.22%。术后6个月与术后3个月椎体融合率比较，腰椎X线( 字2=29.412，P<0.05)、CT扫描重建( 字2=22.121，P<0.05)、MRI( 字2=27.692，P<0.05)；术后1年与术后6个月椎体融合率比较，腰椎X线( 字2=5.063，P<0.05)、CT扫描重建( 字2=4.431，P<0.05)、MRI( 字2=8.134，P<0.05)；术后2年与术后1年椎体融合率比较，腰椎X线( 字2=0.000，P>0.05)、CT扫描重建( 字2=2.532，P>0.05)、MRI( 字2=1.636，P>0.05)。相同时间点三种检查手段在椎体融合率方面比较，差异均无统计学意义(P>0.05)。结论：磁共振在评估腰椎椎体融合术后椎体骨性融合方面与CT扫描重建效果相当，优于腰椎X线片，磁共振评估可作为术后仍有症状的患者融合状态评估方法。

【Abstract】 Objective：To evaluate the clinical value of magnetic resonance imaging in assessing bone fusion after lumbar vertebral fusion.Method：The data of 36 patients with lumbar degenerative disease who underwent transforaminal lumbar interbody fusion(TLIF)from January 2012 to June 2014 were retrospectively analyzed.All patients were followed up for 2 years，X-ray，CT，MRI imaging data were selected，the effect of interbody fusion of different imaging methods postoperative 3 months，6 months，1 year，2 years were assessed.Result：The intervertebral fusion rate of lumbar X-ray，CT scan reconstruction and MRI after 3 months，6 months，1 year and 2 years were 16.67%，8.33%，0；80.56%，61.11% and 55.56%；97.22%，83.33%，86.11%；100%，97.22%，97.22%.After 3 months compared with 6 months，the intervertebral fusion rate of lumbar X-ray ( 字2=29.412，P<0.05)，CT scan reconstruction( 字2=22.121，P<0.05)，MRI( 字2=27.692，P<0.05).After 1 year compared with 6 months，the vertebral fusion rate of lumbar X-ray ( 字2=5.063，P<0.05)，CT scan reconstruction ( 字2=4.431，P<0.05)，MRI( 字2=8.134，P<0.05).After 2 years compared with 1 year，the vertebral fusion rate of lumbar X-ray( 字2=0.000，P>0.05)，CT scan reconstruction( 字2=2.532，P>0.05)，MRI( 字2=1.636，P>0.05).There was no significant difference in vertebral fusion rate among the three methods at the same time point(P>0.05).Conclusion：Magnetic resonance imaging (MRI) is superior to lumbar radiographs in assessing vertebral bone fusion after lumbar vertebral fusion. Magnetic resonance imaging can be used as a method for assessing the fusion status of patients with postoperative symptoms.
