目的:分析局灶性磨玻璃结节(f GGO)MDCT 1 mm薄层重建后的表现,得到早期肺癌磨玻璃结节的影像学特征。方法:分析53例已经活检或抗炎治疗证实有病理结果的肺部磨玻璃结节,分析其影像学征象,包括病变位置、大小、形态、界面、边缘、空泡、支气管扩张及蜂窝征、细支气管充气、胸膜凹陷征、血管聚集增粗以及m GGO中GGO含量,统计分析各征象在良恶性之间的差异。结果:良、恶性fGGO边缘、界面以及血管聚集增粗具有统计学差异,P<0.05;而患者的一般资料、病灶基本信息及病灶形态、空泡支气管蜂窝、细支气管充气、胸膜凹陷以及mGGO中GGO含量在良恶性fGGO的表现差异不明显,P>0.05。结论:MDCT 1 mm薄层重建后的fGGO影像学特征对于鉴别良恶性fGGO及诊断早期肺癌具有极其重要的应用价值。
OBJECTIVE: To analyze the imaging findings of thin-layer reconstruction of focal GGO MDCT 1 mm and obtain the imaging features of ground-glass nodules in early-stage lung cancer. METHODS: Lung biopsies of 53 patients with pathologically confirmed biopsies or anti-inflammatory treatments were analyzed and their imaging findings were analyzed including location, size, morphology, interface, margin, vacuolization, bronchiectasis, Bronchial airway, pleural indentation, thickening of blood vessels and GGO content in m GGO, statistical analysis of the signs of the difference between benign and malignant. Results: There were significant differences in the margins, interface and vascular thickening of fGGO between benign and malignant cases, P <0.05; while the general data of patients, basic information of lesion and lesion morphology, vacuolar bronchial cells, bronchioles, pleura and mGGO GGO content in benign and malignant fGGO performance was not significant, P> 0.05. CONCLUSION: The imaging features of fGGO after MDCT 1 mm thin-layer reconstruction are of great importance in differentiating benign and malignant fGGO and diagnosing early stage lung cancer.
