摘要
目的分析新型冠状病毒肺炎(COVID-19)患者的高分辨率CT(HRCT)影像学特征。方法回顾性分析2020年1—4月于自贡市第一人民医院行COVID-19核酸检测阳性的9例患者的临床资料,所有患者均行HRCT检查,分析影像学特征。结果9例患者共接受了40次HRCT扫描,平均间隔时间4.3 d。分析患者每次HRCT扫描的影像学表现,发现病情最严重时期为入院后第8天,表现为病灶呈大小不等磨玻璃影9例,实变影7例,实变病灶跨肺段但不累及整个肺段,其周围及病灶内可见增粗肺动脉及肺静脉、局部小叶间隔增厚呈铺路石征改变6例,部分血管穿行于病灶内,部分血管呈集束征改变;实变影内见厚壁小支气管穿行6例,但通畅;病灶位于肺外周或胸膜下8例;病灶呈多发6例;病灶内均未见空洞、钙化、淋巴结肿大,少见胸腔积液征象,相邻胸膜轻度增厚。入院9 d后病灶逐步吸收,影像学表现为实变影较前密度减低、变淡,边界出现,磨玻璃影随住院时间延长逐步吸收,部分残留纤维索条影,部分完全吸收,增粗血管恢复至正常状态;对于伴有基础疾病的患者,肺部病灶范围更广,实变影更多,吸收过程变慢。结论COVID-19患者的HRCT影像学表现具有一定的特征,且其特征在疾病诊断、治疗中起着至关重要的作用。
Objective The imaging characteristics of high resolution CT(HRCT)for patients with corona virus disease 2019(COVID-19)were analyzed.Methods The clinical data of 9 positive patients diagnosed by COVID-19 nucleic acid test in Zigong First People's Hospital from January to April 2020 were retrospectively analyzed.They all underwent HRCT examination and then the imaging characteristics were analyzed.Results The 9 patients received HRCT scan for 40 times totally,and the average interval was 4.3 days.The imaging characteristics of HRCT scan of patients for every time were analyzed,it was found that the disease was most severe at the 8th day after admission,the imaging characteristics were as follow:9 cases were with ground glass shadows of different sizes,7 cases were with consolidation shadows,while in 6 cases,consolidation lesions went through lung segments but didn't involve in the whole segments,thickened pulmonary artery and pulmonary vein were found surrounding and within the lesions,local interlobular septum thickened and changed to paving stone sign,some blood vessels crossed in the lesions,some blood vessels changed to bundles;6 cases were with thick-wall little bronchi crossing in consolidation shadow,but presented clear;the lesions of 8 cases were located in peripheral lung or under pleura;6 cases were with multiple lesions;in lesions,cavitation,calcification and lymphadenectasis were not found,little pleural effusion was found,abutting pleura thickened slightly.9 days after admission,lesions were gradually absorbed,the imaging characteristics were as follow:the density of consolidation shadow reduced and it became lighter compared with what it was before,and the boundary appeared,the ground glass shadow was gradually absorbed with the extension of hospitalization time,some were still with residual fiber cord shadows,some were completely absorbed,the thickened blood vessels returned to normal state;as for patients with underlying diseases,the pulmonary lesions'range was more extensive,the amount of consolida
