目的 :探讨肺结节CT性质、实体成分比例与病理学类型的相关性。方法 :根据病理学类型将2011年2月~2016年10月我院收治的260肺结节患者分为A组(35例)、B组(39例)、C组(65例)、D组(121例),其中A组为非典型腺瘤样增生患者、B组为原位腺癌患者、C组为微小浸润性腺癌患者、D组为腺癌患者,现比较4组患者的肺结节CT性质、实体成分比例。结果 :(1)4组研究对象单纯磨玻璃结节、混合磨玻璃结节、实性结节构成比相比差异有统计学意义。A组患者单纯磨玻璃结节构成比显著高于B组、C组、D组,B组患者单纯磨玻璃结节构成比显著高于C组、D组,C组与D组患者之间单纯磨玻璃结节构成比相比差异无统计学意义。4组研究对象之间混合磨玻璃结节构成比相比差异无统计学意义。A组、B组患者实性结节构成比显著低于C组、D组,A组与B组患者之间实性结节构成比相比差异无统计学意义,C组与D组患者之间实性结节构成比相比差异无统计学意义。(2)4组研究对象肺结节实体成分比例相比差异有统计学意义,A组、B组肺结节实体成分比例显著低于C组、D组,A组、B组患者之间肺结节实体成分比例相比差异无统计学意义,C组患者肺结节实体成分比例显著低于D组,差异有统计学意义。结论 :肺结节CT性质、实体成分比例与其病理学类型之间存在一定的相关性,影像学检查发现实性结节或者实体成分比例较高,其诊断为恶性肿瘤的可能性就较大。
Objective: To investigate the correlation between the CT features of pulmonary nodules, the proportion of solid components and the pathological types. Methods: According to the pathological types, 260 patients with pulmonary nodules admitted in our hospital from February 2011 to October 2016 were divided into group A (35 cases), group B (39 cases), group C (65 cases), group D (121 cases), of which A group of patients with atypical adenomatous hyperplasia, B group of adenocarcinoma in situ, C group of patients with micro-invasive adenocarcinoma, D group of patients with adenocarcinoma, pulmonary tuberculosis is now compared 4 patients Section CT nature, the proportion of physical components. Results: (1) There were significant differences between the four groups in terms of the structure of pure ground nodules, mixed ground glass nodules and solid nodules. The composition ratio of simple ground nodules in group A was significantly higher than that in group B, the constituent ratios of simple ground nodules in group C, group D and group B were significantly higher than those in group C, and those in group D, group C and group D Ground glass nodules than the composition of the difference was not statistically significant. There was no significant difference in the composition of mixed ground glass nodules between the 4 groups. The ratio of solid nodules in group A and group B was significantly lower than that in group C, and there was no significant difference in the proportion of solid nodules between group D, group A and group B, and between group C and group D There was no significant difference in the composition of solid nodules between the two groups. (2) There were significant differences in the proportions of pulmonary nodules between the four groups. The proportions of pulmonary nodules in group A and group B were significantly lower than those in group C, group D, group A and group B There was no significant difference in the proportions of nodules between the two groups. The proportion of pulmonary nodules in group C was significantly lower than that in group D, the difference was statistically significant. Conclusion: There is a certain correlation between the CT features and the proportion of the physical components of the pulmonary nodules and the pathological types of the nodules. The higher the proportion of solid nodules or solid components, the higher the possibility of diagnosis of malignant tumors.
