| 摘 要： | 目的:总结新型冠状病毒肺炎磨玻璃密度影（GGO）的高分辨率CT （HRCT）特点，探讨其解剖及病理基础。方法:回顾性分析87例确诊的新型冠状病毒肺炎HRCT影像资料，总结GGO的病灶特点。结果:发现GGO病灶共计255处，病灶分布特点:中央区4处（1.57%），外周区120处（47.06%），胸膜下区131处（51.37%）。病灶结构特点:铺路石征48处（18.82%），小血管增粗191处（74.90%）。病灶边缘特点:弓状凹陷征96处（37.65%），胸膜牵拉征75处（29.41%）。结论:外周分布的磨玻璃密度影是新型冠状病毒肺炎的典型HRCT表现，铺路石征、弓状凹陷征、胸膜牵拉征是病灶机化、纤维化的表现。

| Abstract: | Objective:To summarize the characteristics of COVID-19 ground glass opacity(GGO) on HRCT, and to explore its anatomical and pathological basis.Methods:The HRCT imagings of 87 cases with COVID-19 were analyzed retrospectively and the characteristics of GGO were summed up. Results:A total of 255 GGO lesions were found, and their distribution characteristics were as follows:4 in the central region(1.57%), 120 in the peripheral region(47.06%), and 131 in the subpleural region(51.37%). The structural features of the lesions:48 lesions with paving stone signs(18.82%), and 191 lesions with small thickened blood vessels.The marginal features:96 lesions with arcuate indentations(37.65%) and 75 lesions with pleural traction signs(29.41%). Conclusion:The peripheral distribution of GGO is the typical HRCT manifestation of COVID-19, and paving stone sign, arcuate indentation sign and pleural traction sign are the manifestations of the lesion organization and fibrosis. |
