摘　　要：目的对不同病理类型肺癌伴有孤立肺性结节的64排螺旋CT动态增强扫描影像学特点进行分析总结。方法将我院在2016年3月至2022年3月期间收治的135例肺癌合并有孤立性肺结节患者作为研究对象,按病理类型区分为小细胞癌(15例),腺癌(89例)和鳞癌(31例)。采用64排螺旋CT对所有患者进行检查。比较不同病理类型孤立性肺结节的CT值变化、强化方式、强化净增值、强化率。结果不同病理类型肺癌的孤立性肺结节CT值不同。不同病理类型孤立性肺结节在强化方式方面比较,差异具有统计学意义(P=0.000),其中腺癌孤立性肺结节主要表现为均匀强化(所占比例为77.53%),而鳞癌结节则相反,主要表现为不均匀强化(所占比例为67.74%),小细胞癌孤立性肺结节强化表现不明显。就强化净增值而言,小细胞癌孤立性肺结节明显低于腺癌和鳞癌(P均<0.05),而腺癌孤立性肺结节强化净增值与鳞癌差异不显著(P>0.05);不同病理类型孤立性肺结节强化率方面比较,差异无统计学意义(P>0.05)。结论64排螺旋CT动态增强扫描在鉴别诊断不同病理类型肺癌患者的孤立性肺结节领域具有非常重要的临床价值。Objective To analyze the features of dynamic enhanced 64 row-spiral computerized tomography(CT)for patients with solitary lung cancer nodules with different pathological patterns.Methods A total of 135 patients with lung cancer complicated with solitary pulmonary nodules admitted to our hospital from December 2020 to March 2023 were selected as the research objects.According to pathological types,they were divided into small cell carcinoma(15 cases),adenocarcinoma(89 cases)and squamous cell carcinoma(31 cases).All patients were examined using 64-slice spiral CT.The CT value changes,enhancement methods,enhancement net increment and enhancement rate of isolated pulmonary nodules of different pathological types were compared.Results CT values of isolated pulmonary nodules were different in different pathological types of lung cancer.Different pathological types of isolated lung nodules showed statistically significant differences in enhancement methods(P=0.000),among which adenocarcinoma isolated lung nodules mainly showed uniform enhancement(77.53%),while squamous carcinoma nodules mainly showed uneven enhancement(67.74%).Small cell carcinoma solitary pulmonary nodules showed no enhancement.In terms of enhanced net increment,isolated pulmonary nodules of small cell carcinoma were significantly lower than those of adenocarcinoma and squamous carcinoma(P both&lt;0.05),and there was no significant difference in the enhancement of solitary pulmonary nodules between adenocarcinoma and squamous cell carcinoma(P&gt;0.05);There was no significant difference in the enhancement rate of isolated pulmonary nodules among different pathological types(P>0.05).Conclusions 64-slice spiral CT dynamic enhanced scanning has a very important clinical value in the differential diagnosis of isolated pulmonary nodules in patients with different pathological types of lung cancer.
