SPECT/CT融合显像对肺癌胸壁骨侵犯的诊断价值

目的：探讨SPECT/CT融合显像对肺癌胸壁骨侵犯的诊断价值。方法：回顾性分析47例经临床确诊的患者的影像学资料，比较MSCT与SPECT/CT融合显像对肺癌胸壁骨侵犯的检查结果，进行统计学分析。结果：MSCT的敏感性为68.3％（28/41），特异性为100%（6/6），准确性为72.3%（34/47）；SPECT/CT融合显像的敏感性为97.6％（40/41），特异性为33.3%（2/6），准确性为89.4%（42/47）。2种检查方法结果的差异有统计学意义（0.01＜P＜0.05）。结论：SPECT/CT融合显像相对于MSCT检查，可明显提高对肺癌胸壁骨侵犯的检出率，降低MSCT的漏诊率，具有很好的临床应用价值。

The value of the SPECT/CT fusion images in the diagnosis of the chest wall bone invasion of lung cancer

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.
