摘要
目的分析CT能谱扫描及40 keV对应CT值等参数对肺内良性肿块及恶性肿块的诊疗价值。方法选取行胸部CT或者X线首次显示肺内有肿块患者126例,良性组患者38例,包含慢性与急性的活动性炎症,如化脓性肺炎、机化性肺炎、炎性假瘤和结核等,肿瘤组患者88例,均为非小细胞周围型的肺癌。对以上患者进行能谱CT检测,单因素方差分析恶性组与良性组间患者40 keV所对CT数值、碘浓度、能谱的曲线斜率与水浓度。结果恶性组患者碘浓度为(0.80±0.18),明显低于良性组的(1.50±0.20),差异有统计学意义(P <0.05);恶性组患者斜率为(0.90±0.18),明显低于良性组的(1.68±0.31),差异有统计学意义(P <0.05);肿瘤组患者40 keV时所对CT值为(81.74±16.63),明显低于良性组的(140.16±18.07),差异有统计学意义(P <0.05); 2组患者在水浓度方面差异无统计学意义(P>0.05)。结论 CT能谱成像结合40 keV所对CT数值、碘浓度、能谱曲线斜率与水浓度等多个参数进行定量分析,对肺部良恶性肿块有较高的诊断价值。
Objective To analyze the diagnostic and therapeutic value of CT spectrum scanning and 40 keV corresponding CT value in benign and malignant pulmonary masses.Methods From June 2015 to June 2017 in our hospital for chest CT or X-ray showed for the first time in 126 cases of tumor patients,38 cases of benign patients,including acute and chronic inflammation,such as suppurative pneumonia,organizing pneumonia,tuberculosis and inflammatory pseudotumor,88 cases of tumor patients,all around non small cell lung cancer patients of the above type; energy spectrum CT test,single factor analysis of variance with 40 keV tumor group and benign group between the slope water and the concentration of CT value,iodine concentration,energy spectrum.Results The iodine concentration in the tumor group was( 0.80 ± 0.18),Significantly lower than the benign group( 1.50 ± 0.20),there was statistically significant difference( P < 0.05); The slope of the tumor group was( 0.90 ± 0.18),Significantly lower than the benign group( 1.68 ± 0.31),there was statistically significant difference( P < 0.05); tumor patients when the CT value is( 81.74 ± 16.63) was significantly lower than that in benign group( 140.16 ± 18.07),there was statistically significant difference( P < 0.05); There was no statistically significant difference in water concentration between the two groups( P >0.05).Conclusion CT energy spectrum imaging combined with 40 keV quantitative analysis of CT value,iodine concentration,energy spectrum curve slope and water concentration,has a higher value in the diagnosis of lung benign and malignant tumor.
