摘要:
目的 分析能谱CT成像鉴别实性肺癌病理类型的定量参数及诊断作用。方法 选取2019年10月-2021年10月经天津市静海区医院确诊的78例实性肺癌病例，给予能谱CT成像检查，对其定量参数及诊断作用进行分析。结果 平扫能谱CT定量参数Eff-Z（有效原子序数）、钙（水）浓度及能谱曲线斜率（K40-65keV）由大到小依次为腺癌＞鳞癌＞小细胞肺癌（P＜0.05）；动脉期能谱CT定量参数标准化碘浓度（NIC）及K40-65keV由大到小依次为腺癌＞鳞癌＞小细胞肺癌（P＜0.05）。经ROC曲线分析显示，平扫参数[钙(水)浓度、Eff-Z、K40-65keV]与动脉期参数（NIC、K40-65keV）诊断小细胞肺癌与非小细胞肺癌的曲线下面积分别为0.65、0.63、0.68、0.70、0.57，诊断肺腺癌与鳞癌的曲线下面积分别为0.65、0.66、0.64、0.72、0.63。不同病理类型实性肺癌平扫能谱衰减曲线走势分型比较，差异有统计学意义（P＜0.05），其中腺癌多表现为Ⅲ型，鳞癌主要为Ⅱ型，小细胞肺癌则集中在Ⅳ型。结论 能谱CT成像定量参数在不同病理类型的实性肺癌中存在差异，对肺腺癌、鳞癌及小细胞肺癌均具有确切的鉴别诊断价值。
Abstract:
Objective To analyze the quantitative parameters and diagnostic effects of energy spectrum CT imaging in identifying the pathological types of solid lung cancer.Methods A total of 78 solid lung cancer cases diagnosed by Tianjin Jinghai Hospital from October 2019 to October 2021 were selected for energy spectrum CT imaging, and their quantitative parameters and diagnostic effects were analyzed.Results The quantitative parameters Eff-Z (effective atomic number), calcium (water) concentration and energy spectrum curve slope (K40-65keV) of plain energy spectrum CT in descending order were adenocarcinoma>squamous cell carcinoma>small cell lung cancer (P<0.05); the normalized iodine concentration (NIC) and K40-65keV of spectral CT quantitative parameters in arterial phase were adenocarcinoma>squamous cell carcinoma>small cell lung cancer (P<0.05). (P<0.05). ROC curve analysis showed that the area under the curve of plain scan parameters [calcium (water) concentration, Eff-Z, K40-65keV] and arterial phase parameters (NIC, K40-65keV) in the diagnosis of small cell lung cancer and non-small cell lung cancer were 0.65, 0.63, 0.68, 0.70, 0.57, respectively; the area under the curve of lung adenocarcinoma and squamous cell carcinoma was 0.65, 0.66, 0.64, 0.72, 0.63, respectively. Different pathological types of solid lung cancer had differences in the trend classification of the flat scan energy spectrum attenuation curve (P<0.05), Among them, adenocarcinoma was mostly type Ⅲ, squamous cell carcinoma was mainly type Ⅱ, and small cell lung cancer was concentrated in type Ⅳ.Conclusion There are significant differences in the quantitative parameters of energy spectrum CT imaging in solid lung cancer of different pathological types, and it has a definite differential diagnosis value for lung adenocarcinoma, squamous cell carcinoma and small cell lung cancer.
