Abstract

Objective: To evaluate the value of SPECT/CT fused images in the diagnosis of the chest wall bone invasion of lung cancer. Methods: The imaging data of 47 cases of patients who underwent MSCT and SPECT/CT were retrospectively analyzed. The detection rate of different methods was compared． Resluts: MSCT for diagnosis of the chest wall bone invasion of lung cancer had a sensitivity of 68.3％(28/41), specificity of 100％(6/6), accuracy of 72.3％(34/47). SPECT/CT for diagnosis of the chest wall bone invasion of lung cancer had a sensitivity of 97.6％(40/41), specificity of 33.3%(2/6), accuracy of 89.4%(42/47), and there was statistical significance(P＜0.05). Conclusions: The SPECT/CT fusion images not only obviously improve the detection rate of the chest wall bone invasion of lung cancer, but the missed diagnostic rate are also lower than MSCT, so have very good value.
