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.
