摘要
目的研究CT影像学特征与亚厘米肺结节病理诊断的相关性。方法回顾性分析2020年至2023年在我院行手术切除的208例压厘米肺小结节患者的临床资料,按照病理结果分为良性病变(BL)、肺部不典型腺瘤样增生(AAH)18例、肺部原位癌(AIS)65例、肺部微浸润腺癌46例、肺部浸润性腺癌(IAC)51例,所有患者均接受常规CT及增强CT检查,分析CT形态特征分类以及肺结节尺寸和增强程度与临床病理的关系。结果208例亚厘米肺小结节患者均为单发结节,根据不同形态特征可分为Ⅰ型90例、Ⅱ型38例、Ⅲ型16例、Ⅳ型51例、Ⅴ型13例,BL组、AAH组、AIS组、MIA组、IAC组Ⅰ型、Ⅱ型、Ⅲ型、Ⅳ型、Ⅴ型形态特征分类比较差异有统计学意义(χ^(2)=107.282,P<0.001);BL组、AAH组、AIS组、MIA组、IAC组亚厘米肺小结节尺寸大小比较,差异有统计学意义(F=14.562,P<0.001),其中IAC组的亚厘米肺小结节尺寸最大,均高于其他组,AAH组、AIS组、MIA组、IAC组肺小结节尺寸均大于BL组,差异有统计学意义(P<0.05)。BL组、AAH组、AIS组、MIA组、IAC组亚厘米肺小结节增强程度比较差异有统计学意义(χ^(2)=52.338,P<0.001),IAC组肺结节显著增强的比例最高,为58.82%,高于其他4组,差异有统计学意义(P<0.05)。结论常规CT形态特征分类以及增强CT下的肺结节尺寸和增强程度对亚厘米肺小结节的定性诊断有着较大价值。
Objective To study the correlation between T imaging features and the pathological diagnosis of subcentimeter pulmonary nodules.Methods The clinical data of 208 patients with small cm pulmonary nodules from our hospital from 2020 to 2023,according to the pathological results were divided into benign lesions(BL),18 cases of pulmonary atypical adenoma hyperplasia(AAH),65 cases of pulmonary carcinoma in situ(AIS),46 cases of pulmonary microinvasive adenocarcinoma,51 cases of pulmonary invasive adenocarcinoma(IAC),all patients received conventional CT and enhanced CT examination,analyze CT morphological classification of characteristics and the relationship between the size and enhancement of pulmonary nodules and clinical pathology.Results All 208 patients with subcentimeter pulmonary nodules were single nodules,According to different morphological characteristics,typeⅠcan be divided into 90,38,16,51,13 V,Between BL,AAH,AIS,MIA,typesⅠ,type,Ⅴand IAC(χ^(2)=107.282,P<0.001);Comparison of size of subcentimeter pulmonary nodules in BL,AAH,AIS,MIA and IAC groups,Statistically significant difference(F=14.562,P<0.001),Of the subcentimeter pulmonary nodules were the largest in the IAC group,Are higher than those in the other groups,The size of pulmonary nodules in AAH,AIS,MIA and IAC groups were larger than those in BL group,The difference was statistically significant(P<0.05).The difference of subcentimeter lung nodules in the BL,AAH,AIS,MIA,and IAC groups(χ^(2)=52.338,P<0.001),and the IAC group was 58.82%,higher than the other four groups(P<0.05).Conclusion The conventional classification of CT morphological features and the size and enhancement of pulmonary nodules under enhanced CT are of great value for the qualitative diagnosis of subcentimeter pulmonary nodules.
