      The additional value of 99mTc-MDP SPECT/CT for diagnosing lumbar spondylolysis

      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 as sessed.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.
