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.关键词
