在这项回顾性研究中，对2019年121例感染冠状病毒病的症状性患者进行了胸部CT扫描。对2020年1月18日至2020年2月2日期间来自中国四个中心的2019冠状病毒病（COVID-19）患者的常见CT表现与症状发作和首次CT扫描之间的时间关系进行了审查（即，早期，0-2天[36例患者];中期，3-5天[33例患者];晚期，6-12天[25例患者]）。COVID-19感染的影像学特征是双侧和外周磨玻璃样和实变性肺阴影。值得注意的是，在早期阶段成像的36名患者中有20名（56%）的CT扫描正常。随着发病时间的延长，CT表现更频繁，包括实变、双侧和外周病变、更大的全肺受累、线性阴影、疯狂铺路图案和反向晕征。在36例早期患者中的10例（28%）、33例中期患者中的25例（76%）和25例晚期患者中的22例（88%）中观察到双侧肺受累。(C)RSNA，2020年
In this retrospective study, chest CT scans from 121 symptomatic patients infected with coronavirus disease 2019 (COVID-19) from four centers in China from January 18, 2020, to February 2, 2020, were reviewed for common CT findings in relationship to the time between symptom onset and the initial CT scan (ie, early, 0-2 days [36 patients]; intermediate, 3-5 days [33 patients]; late, 6-12 days [25 patients]). The hallmarks of COVID-19 infection on images were bilateral and peripheral ground-glass and consolidative pulmonary opacities. Notably, 20 of the 36 patients (56%) imaged in the early phase had a normal CT scan. With a longer time after the onset of symptoms, CT findings were more frequent, including consolidation, bilateral and peripheral disease, greater total lung involvement, linear opacities, crazy-paving pattern, and the reverse halo sign. Bilateral lung involvement was observed in 10 of the 36 early patients (28%), 25 of the 33 intermediate patients (76%), and 22 of the 25 late patients (88%). (C) RSNA, 2020
