摘　　要：目的 探讨新型冠状病毒肺炎(COVID-19)的早期CT表现及其在早期诊断中的作用.方法 筛选2020年1月1日~1月30日间华中科技大学同济医学院附属同济医院收治的21例2019-nCoV核酸检测阳性的肺炎患者,回顾性分析其病程3 d以内CT检查的影像学表现,并对肺部CT异常病灶的数目、位置、分布、密度及其他征象进行分析.结果 CT扫描发现21例COVID-19患者早期CT表现中单发病灶9例(42.9%),多发病灶12例(57.1%);单发病灶以右肺下叶为主共6例;所有病例的病灶分布主要以双肺下叶及肺的外周部为主,其中右肺下叶17例(80.9%),左肺下叶11例(52.4%),以外周分布为主的15例(71.4%);影像学表现中密度以间质性改变最多,共14例(66.7%),其次为磨玻璃影共11例(52.4%),单纯实变影较少见仅2例,胸腔积液1例.结论 胸部CT扫描能早期发现COVID-19患者肺部的异常改变.其肺部CT早期改变有一定的特点,因此,胸部CT检查在COVID-19患者的筛查及早期诊断中有重要作用.Objective To investigate the early CT findings of 2019 coronavirus disease(COVID-19)and the role in early diagnosis.Methods From January 1,2020 to January 30,2020,21 pneumonia patients positive for 2019-nCoV nucleic acid test in our hospital were screened The imaging findings of CT within 3 days of the course of disease were retrospectively analyzed,and the number,location,distribution,density and other signs of abnormal lesions detected by CT in the lung were analyzed.ResultsIn the early CT findings of 21 patients with COVID-19,there were 9 cases with single lesions(42.9%)and 12 cases with multiple lesions(57.1%);single lesions in 6 cases were mainly located in the lower lobe of the right lung,and the lesions of all the cases were mainly distributed in the lower lobe of both lungs and the peripheral part of lungs.Among them,there were 17 cases(80.9%)with lesions of the right lower lobe,11 cases(52.4%)with lesions of the left lower lobe,and 15 cases(71.4%)dominated by the periphery lesions.The interstitial change of image density was the most common,with a total of 14 cases(66.7%),followed by ground glass shadow in 11 cases(52.4%),and solid shadow in only 2 cases,while pleural effusion was rare in only 1 case.Conclusion Chest CT scan can detect early abnormal pulmonary changes in patients with COVID-19.The early changes of pulmonary CT in patients with COVID-19 are characteristic,therefore,plain chest CT scan plays an important role in the screening and early diagnosis of COVID-19.
