目的：介绍来自中国两个中心的21例2019冠状病毒病（COVID-19）病例的CT和胸部X线检查结果，以及5例病例的随访影像学检查结果。材料和方法：这是一项在深圳和香港进行的回顾性研究。纳入了COVID-19感染患者。对已发表的关于COVID-19感染放射学特征的文献进行了系统综述。结果：主要影像学表现为磨玻璃影，偶见周边实变影。所有病例均无胸腔积液和淋巴结肿大。患者表现为毛玻璃样阴影演变为实变，随后解决了空域变化。CT上可见的磨玻璃样影和实变影有时在胸部X线片上无法检测到，这表明CT是一种更敏感的检查成像方式。该系统综述确定了另外4项研究，证实双侧和外周磨玻璃样改变伴或不伴实变是CT胸部检查的主要发现。结论：COVID-19感染的肺部表现主要以CT上的磨玻璃影为特征，偶尔有实变。深圳和香港患者的影像学结果与其他研究中心的4篇既往文献一致。(c)RSNA，2020年
Purpose: To present the findings of 21 coronavirus disease 2019 (COVID-19) cases from two Chinese centers with CT and chest radiographic findings, as well as follow-up imaging in five cases. Materials and Methods: This was a retrospective study in Shenzhen and Hong Kong. Patients with COVID-19 infection were included. A systematic review of the published literature on radiologic features of COVID-19 infection was conducted. Results: The predominant imaging pattern was of ground-glass opacification with occasional consolidation in the peripheries. Pleural effusions and lymphadenopathy were absent in all cases. Patients demonstrated evolution of the ground-glass opacities into consolidation and subsequent resolution of the airspace changes. Ground-glass and consolidative opacities visible on CT are sometimes undetectable on chest radiography, suggesting that CT is a more sensitive imaging modality for investigation. The systematic review identified four other studies confirming the findings of bilateral and peripheral ground glass with or without consolidation as the predominant finding at CT chest examinations. Conclusion: Pulmonary manifestation of COVID-19 infection is predominantly characterized by ground-glass opacification with occasional consolidation on CT. Radiographic findings in patients presenting in Shenzhen and Hong Kong are in keeping with four previous publications from other sites. (c) RSNA, 2020
