Abstract: Objective To evaluate the diagnostic value of 99Tcm-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 followup.The diagnostic sensitivity and accuracy of SPECT,CT and SPECT/CT images were calculated and x2 test was performed to analyze the data.Results Twenty-eight patients were diagnosed as lumbar spondylolysis.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(x2=28.13,P＜ 0.05).Conclusion SPECT/CT bone scan may detect lumbar spondylolysis in early stage.
