摘要
目的分析探讨CT能谱成像鉴别肺结核结节与肺癌的价值。方法回顾性分析56例肺部结节病例的能谱特征,比较肺癌与肺结核不同ke V下CT值、碘浓度及斜率。结果肺结核在不同的ke V下的CT值、碘浓度均低于肺癌,斜率则高于肺癌。结论 GSI定量参数对肺癌与肺结核结节鉴别诊断有一定帮助。
Objective To analyze the value of CT energy spectrum imaging in differentiating lung cancer and tuberculosis. Methods The spectral characteristics of 56 cases of pulmonary nodules were analyzed retrospectively,CT values,iodine concentration and slope of the different ke V values of lung cancer and pulmonary tuberculosis were compared. Results The CT value and iodine concentration of pulmonary tuberculosis in different ke V for tuberculosis were lower than that of lung cancer,the slope was higher. Conclusion GSI quantitative parameters can be helpful to the differential diagnosis of lung cancer and pulmonary tuberculosis.
