摘　　要：目的观察分析新型冠状病毒肺炎的CT表现及影像学分型,探讨CT在临床治疗决策中的价值。方法回顾性分析2022年12月20日至2023年1月20日期间本院确诊COVID-19的116例患者CT资料,分析其CT表现及影像学分型。结果92例(79.31%)病灶以外周分布为主,81例(69.83%)病灶以两肺中下叶分布为主,102例(87.93%)病灶多发。病灶总计1,006个,859个病灶呈磨玻璃密度,占85.39%;902个病灶形态呈片状,占89.66%。病灶中出现铺路石征17例(14.66%),充气支气管征42例(36.21%),伴有心包积液11例(9.48%),胸腔积液13例(11.21%)。影像学分型:轻型86例(74.14%),进展型19例(16.38%),重型11例(9.48%)。结论新型冠状病毒肺炎患者CT表现有一定的特征性,以多发、片状、两肺中下叶外周分布为主的磨玻璃影多见。CT能做影像学分型,结合临床资料,可以为临床诊治提供一些参考依据。Objective To Observe and analyze the CT appearances and classification in Coronavirus disease 2019(COVID-19)with the objective of exploring the value of CT in clinical treatment decision-making.Methods The CT data of 116 patients diagnosed with COVID-19 were retrospectively analyzed for CT appearances and imaging classifications in the Third Affiliated Hospital of Wenzhou Medical University from December 20,2022 to January 20,2023.Results A total of 92 cases(79.31%)had peripheral lesions,81 cases(69.83%)had lesions predominantly distributed in the middle and lower lobes of both lungs,and 102 cases(87.93%)had multiple lesions.In total,there was a total of 1006 lesions,of which 859 exhibited ground-glass density(85.39%)and 902 were flaky(89.66%).There was 17 cases(14.66%)of paving stone sign,42 cases(36.21%)of inflatable bronchial sign,11 cases(9.48%)of pericardial effusion,and 13 cases(11.21%)of pleural effusion.Imaging classifications showed that 86 cases(74.14%)were mild,19(16.38%)were progressive,and 11(9.48%)were severe.Conclusion CT images of patients with COVID-19 exhibit certain characteristics,including multiplied,flaky ground-glass opacities in both the middle and lower lobes of both lungs.Combing CT with clinical data can provide some reference for clinical decision-making.
