摘要
目的本文旨在分析不同病理种类直径≤1cmpGGN肺腺癌MSCT影像学征象。方法收集本院2017年4月至2019年11月收治的87例肺腺癌患者临床资料,所有患者均经病理检查确诊,对不同病理类型患者MSCT图像进行分析,总结病灶基本影像学特征:病变部位、大小、密度、CT值、病灶边缘情况、“空泡”征、“空气支气管”征、肺瘤界面、血管情况等。结果AAH、AIS、MIA、IA四者病变大小、血管改变情况、瘤肺界面存在差异(P<0.05),IA病变最大为(0.87±0.17)cm,AAH与其他三者病变大小差异有统计学意义(P<0.05),其余两两之间比较并无意义(P>0.05)。AAH仅5.88%患者出现血管改变情况,MIA出现几率最多为68.75%;四者瘤肺界面均以清楚为主。结论不同病理种类直径≤1cm纯磨玻璃密度肺腺癌在一些MSCT影像学征象存在差异,随着病情进展,病变增大,血管改变情况越明显,瘤肺界面更清楚。
Objective the purpose of this article is to analyze MSCt imaging signs of lung adenocarcinoma with diameters≤1 cmpGGN in different pathological types.Methods the clinical data of 87 patients with lung adenocarcinoma admitted in our hospital from April 2017 to November 2019 were collected.All patients were confirmed by pathological examination.the MSCt images of patients with different pathological types were analyzed,and the basic imaging characteristics of the lesions were summarized:Lesion location,size,density,Ct value,margins of lesion,vacuole signs,air bronchogram,interface of lung tumor,and vascular conditions.Results there were differences in lesion size,vascular changes,and interface of lung tumor in AAH,AIS,MIA,and IA(P<0.05).the largest IA lesion was(0.87±0.17)cm.the difference in the size of the lesion between AAH and the other three was statistically significant(P<0.05),and there was no significant difference in comparison between the other two pairs(P>0.05).Only 5.88%of patients with AAH had vascular changes,and the maximum probability of MIA was 68.75%.the interface of lung tumor of the four tumours were mainly clear.Conclusion Different pathological types of lung adenocarcinoma with pure ground glass density≤1 cm in diameter differ in some MSCt imaging signs.As the disease progresses,the lesions increase,the more obvious changes in blood vessels are,and the tumor-lung interface become clearer.
