摘　　要：目的:探讨能谱CT多参数成像对周围型肺癌与肺炎性肿块的鉴别诊断价值。方法:选取2018年10月—2022年9月就诊于益阳市中心医院的84例周围型肺癌及炎性肿块患者,其中周围型肺癌组68例,炎性肿块组16例。所有患者均行能谱CT平扫及增强扫描。结果:肺部炎性肿块患者的能谱曲线斜率(λHU 40~70 keV)、碘含量、标准化碘浓度在动脉期及静脉期均显著高于周围型肺癌患者(P<0.01)。肺部炎性肿块患者有效原子序数在平扫、动脉期及静脉期均显著低于周围型肺癌患者(P<0.01)。结论:能谱CT多参数成像能够为周围型肺癌及肺炎性肿块的鉴别诊断提供帮助。Objective To explore the application of spectral CT multi-parameter in the differential diagnosis of peripheral lung cancer and pulmonary inflammatory lump.Methods Select 84 patients with peripheral lung cancer and inflammatory lump who visited Yiyang Central Hospital from October 2018 to September 2022,including 68 patients with peripheral lung cancer and 16 patients with inflammatory lump.All patients underwent chest plain and enhanced CT scan with gemstone spectral imaging.Results The slope of curve(λHU 40-70keV),the iodine concentration(IC)and normalized iodine concentration(NIC)of the pulmonary inflammatory lump patients were significantly higher than those in the peripheral lung cancer patients in the arterial and venous stages(P<0.01).The effective atomic number(Z-effective)of pulmonary inflammatory lump patients was significantly lower than that in the peripheral lung cancer patients in the plain scan,arterial stage and venous stage(P<0.01).Conclusion Spectral CT multi-parameter can provide help in the differential diagnosis of peripheral lung cancer and pulmonary inflammatory lump.
