摘要
目的探讨新型冠状病毒肺炎(COVID-19)初次胸部HRCT影像学表现。方法回顾性收集2020年1月17日—2月17日发热门诊3~10 d后经核酸检测阳性的20例COVID-19初诊患者及同期45例非COVID-19肺炎患者胸部HRCT资料,对病灶分布、密度、形态、大小及伴随征象进行统计和分析。结果COVID-19组142个病灶双肺(96.5%)、外周带(69.7%)、后部(82.4%)分布构成比高于非COVID-19肺炎组(57.3%、37.1%、57.3%),COVID-19组病灶类扇形(54.2%)、GGO(51.4%)、混合GGO(35.2%)、铺路石征(31.7%)、病灶内小血管增粗(43.7%)构成比高于非COVID-19肺炎组(2.4%、32.3%、37.9%、2.4%、7.3%),差异均有统计学意义(P<0.05)。结论COVID-19病灶为两肺多发,外周、肺叶后部分布为主,HRCT主要表现肺间质为主的GGO、混合GGO、铺路石征改变,具有一定的影像特征性,能为COVID-19诊断提供依据。
Objective To investigate initial HRCT findings of the chest with coronavirus disease 2019(COVID-19).Methods The initial HRCT of 20 COVID-19 patients who were tested positive for nucleic acid 3-10 days later and 45 non COVID-19 pneumonia from January 17 to February 17,2020 was retrospectively collected,and the lesions distribution,morphology,size,density and accompanying signs were analyzed.Results The proportion of bilateral lung(96.5%),peripheral band(69.7%),posterior(82.4%)of 142 lesions in the COVID-19 group was higher than that in the non COVID-19 group(57.3%,37.1%,57.3%).The proportion of fan-shaped lesions(54.2%),GGO(51.4%),mixed GGO(35.2%),crazy paving pattern(31.7%)and small vessel thickening in the lesions(43.7%)in the COVID-19 group was higher than that in the non COVID-19 group(2.4%,32.3%,37.9%,2.4%,7.3%).The difference was statistically significant(P<0.05).Conclusion Most lesions of COVID-19 are in bilateral lung,mainly distributed in the peripheral and posterior lobes.HRCT shows the images of GGO,mixed GGO and crazy-paving pattern in the pulmonary interstitium.The chest HRCT has certain imaging characteristics,which can provide basis for the diagnosis of COVID-19.
