摘要
目的 探讨SPECT/CT对腰椎融合术后疼痛原因的诊断价值.方法 对2009年1月至2015年12月53例[男31例,女22例,年龄（42.3±5.3）岁]腰椎融合术后腰背部疼痛而解剖影像学检查未能明确诊断的患者,行SPECT/CT显像探查原因.疼痛原因最终诊断综合临床症状、影像学及临床疗效作出,所有病例随访时间大于6个月.计算SPECT/CT显像的诊断效能.结果 SPECT/CT显像提示螺钉松动23例,椎间融合器无菌性炎性反应6例,撞击综合征9例,15例阴性.SPECT/CT对腰椎融合术后疼痛原因诊断的灵敏度为71.7%（38/53）;对内固定器造成并发症诊断的灵敏度及阳性预测值均为100%（38/38）.结论 SPECT/CT显像在解剖影像学检查未能明确腰椎融合术后疼痛原因时,可为临床提供有价值的参考信息.
Objective To evaluate the value of SPECT/CT for detecting the causes of lumbago in post-lumbar spinal fusion patients. Methods From January 2009 to December 2015, 53 patients （31 males, 22 females, age： （42.3±5.3） years） with lumbago after lumbar spinal fusion, without positive CT and digital radiography （DR） findings, were included in this study and were further examined by SPECT/CT imaging. The final diagnosis was made according to clinical symptoms, multimodality imaging findings, and treatment outcome. All patients were followed up for at least 6 months. Results Thirty-eight patients had positive findings with SPECT/CT imaging, including 23 patients with screw loosening, 6 patients with lumbar fusion cage aseptic inflammation and 9 patients with impingement. The other 15 patients had negative results. The diagnostic sensitivity of SPECT/CT for detecting causes of lumbago was 71.7% （38/53）. The diagnostic sensitivity and positive predictive value of SPECT/CT for complications caused by internal fixators were both 100% （38/38）. Conclusion SPECT/CT scanning could be a clinical valuable tool for inspecting the cause of lumbago in post-lumbar spinal fusion patients.
