摘要目的：探讨99mTc-MDP SPECT/CT对腰椎峡部裂的诊断增益价值。方法：回顾性分析45例临床确诊腰椎峡部裂患者的99mTc-MDP SPECT/CT资料，观察影像学特征，评价其对腰椎峡部裂的诊断增益价值。结果：45例患者92个峡部裂。CT、SPECT及SPECT/CT显像对腰椎峡部裂的诊断灵敏度分别为100％（92/92）、34.78％（32/92）和100％（92/92），准确率分别为100％（92/92）、34.78％（32/92）和100％（92/92）。CT、SPECT及SPECT/CT显像对不稳定性峡部裂的诊断灵敏度分别为44.00%（22/50）、64.00%（32/50）、100.00%（92/92），特异度均为100.00%，准确率分别为69.57%（64/92）、91.30%（84/92）、100.00%（92/92）。经比较，SPECT/CT及CT对峡部裂的诊断准确率两者之间差异无统计学意义（P＞0.05），但均高于SPECT（P＜0.05）。SPECT/CT对峡部裂的不稳定性诊断灵敏度、准确率均高于SPECT和CT显像（P＜0.05）。结论：99mTc-MDP SPECT/CT显像对腰椎峡部裂，尤其是不稳定性峡部裂的诊断具有增益价值。

Abstract：Objective: To evaluate the additional value of 99mTc-MDP SPECT/CT for diagnosing lumbar spondylolysis. Methods: 99mTc-MDP SPECT/CT data of 45 patients with lumbar spondylolysis were analyzed retrospectively. The features of 99mTc-MDP SPECT/CT were observed and the accuracy of 99mTc-MDP SPECT/CT in diagnosing lumbar spondylolysis was assessed. Results: Forty-five patients with 92 spondylolysis were diagnosed． Sensitivities of CT, SPECT and SPECT/CT imaging for the diagnosis of lumbar spondylolysis were 100%(92/92), 34.78%(32/92) and 100%(92/92), the accuracy rate were 100%(92/92), 34.78%(32/92) and 100%(92/92). Sensitivities of CT, SPECT and SPECT/CT imaging of instability spondylolysis were 44.00%(22/50), 64.00%(32/50), 100.00%(92/92), specificities were 100.00%, and with accuracy rates of 69.57%(64/92), 91.30%(84/92), 100.00%(92/92) respectively. There was no statistical difference of diagnostic accuracy between SPECT/CT and CT for spondylolysis(P>0.05), but both of them were higher than SPECT(P<0.05). For unstable spondylolysis, sensitivity and accuracy rate of SPECT/CT was higher than SPECT and CT(P<0.05). Conclusion: 99mTc-MDP SPECT/CT bone imaging has additional value of spondylolysis, especially the unstable spondylolysis diagnosis.
