摘　　要：目的探讨99Tcm-MDP SPECT／CT骨显像对腰椎峡部裂的诊断价值。方法回顾性分析2012年1月至2014年5月间58例下腰背部疼痛患者（男28例，女30例；平均年龄61．3岁）SPECT骨扫描平面采集及腰椎SPECT／CT融合显像资料，综合SPECT／CT和随访CT结果作为诊断标准，分别计算SPECT显像、CT和SPECT／CT融合显像诊断腰椎峡部裂的灵敏度和准确性，不同方法的诊断结果比较采用χ2检验。结果58例患者中，28例患者诊断为腰椎峡部裂。SPECT显像、CT及SPECT／CT融合显像对腰椎峡部裂的诊断灵敏度分别为53．6％（15／28）、78．6％（22／28）和100％（28／28），诊断准确性分别为48．3％（28／58）、89．7％（52／58）和93．1％（54／58）；SPECT／CT融合显像的诊断准确性高于SPECT显像（χ2=28．13，P〈0．05）。结论SPECT／CT骨显像对腰椎峡部裂早期诊断有良好的应用价值。Objective To evaluate the diagnostic value of 18Tcm-MDP SPECT/CT in the diagnosis of lumbar spondylolysis. Methods A total of 58 patients （28 males, 30 females, average age 61.3 years） who underwent bone scan and SPECT/CT because of low back pain from January 2012 to May 2014 were retrospectively evaluated. The final diagnosis was based on comprehensive results of SPECT/CT and follow- up. The diagnostic sensitivity and accuracy of SPECT, CT and SPECT/CT images were calculated and χ2 test was performed to analyze the data. Results Twenty-eight patients were diagnosed as lumbar spondylol- ysis. The diagnostic sensitivities of SPECT, CT and SPECT/CT were 53.6% （15/28） , 78.6% （22/28） and 100%（28/28）. The diagnostic accuracies of SPECT, CT and SPECT/CT were 48.3% （28/58） , 89.7% （52/58） and 93.1%（54/58）. SPECT/CT was proved to be more accurate than SPECT（χ2= 28.13, P〈 0. 05）. Conclusion SPECT/CT bone scan may detect lumbar spondylolysis in early stage.
