| 摘 要： | 目的:探讨能谱CT成像定量分析在鉴别诊断周围型肺癌和肺炎性肿块中的价值。方法:研究对象选择2011年7月至2015年2月在我院进行治疗的肺部孤立肿块患者共84例,将其分为周围型肺癌组38例和肺炎性肿块组46例,对所有患者进行能谱CT成像定量分析,观察其检查结果,分析其诊断价值。结果:静脉期下周围型肺癌在不同ke V的CT值均明显高于肺炎性肿块组,两组比较具有显著差异(P<0.05),动脉期下周围型肺癌在不同ke V的CT值均明显高于肺炎性肿块组,两组比较具有显著差异(P<0.05),周围型肺癌的碘浓度与能谱斜率在动静脉期与肺炎性肿块具有显著差异(P<0.05),而水浓度无显著差异(P>0.05)。结论:采用能谱CT成像定量分析对于周围型肺癌和肺炎性肿块的鉴别诊断准确性较高,具有良好的临床价值。

| Abstract: | Objective: To research CT imaging spectroscopy quantitative analysis of value in the differential diagnosis of peripheral lung cancer and pneumonia in the mass. Methods: Retrospective analysis in July 2011 to February 2015 to our hospital for treatment of patients with solitary pulmonary mass total 84 cases as of this study will be divided into around 38 cases of lung cancer patients and 46 patients with pneumonia mass cases of patients with CT imaging spectroscopy quantitative analysis, observed in patients with test results, analyze its diagnostic value. Results: vein CT values of peripheral lung cancer patients in different keV pneumonia were significantly higher than mass group, the two groups have significant difference (P<0.05), peripheral artery CT values in patients with lung cancer were significantly different keV higher than pneumonia mass group, the two groups have significant difference (P<0.05), iodine concentration and the slope of the energy spectrum of patients with peripheral lung cancer and pneumonia in arteriovenous mass of patients had significant differences (P<0.05), and water There was no significant difference (P>0.05) concentrations. Conclusions: CT imaging spectroscopy for quantitative analysis of high peripheral lung cancer and pneumonia mass differential diagnosis accuracy, a good clinical value. |
