摘要:

在新型冠状病毒肺炎(COVID-19)全球大流行的时代,输入型COVID-19病例给许多国家的疫情防控带来巨大挑战。对于COVID-19的检测和诊断,胸部CT检查可以作为核酸检测结果的有效补充手段。我们报道了中国北京第一例由输入型病例获得COVID-19感染的患者。我们发现胸部CT上结节性病变是该COVID-19患者的早期影像学表现, 深度学习(deep learning,DL)辅助诊断系统定量监测患者肺部病变的发展情况,并及时预警为疑似肺炎,由此我们迅速对该患者进行了医学隔离。经核酸检测,患者最终被确诊为COVID-19,因而社区传播获得了及时的控制。本文进一步讨论了基于DL的CT辅助诊断系统在协助医生筛查和预警COVID-19疑似病例过程中的作用。

Abstract:

In the era of coronavirus disease 2019 (COVID-19) pandemic, imported COVID-19 cases pose great challenges to many countries. Chest CT examination is considered to be complementary to nucleic acid test for COVID-19 detection and diagnosis. We report the first community infected COVID-19 patient by an imported case in Beijing, which manifested as nodular lesions on chest CT imaging at the early stage. Deep Learning (DL)-based diagnostic systems quantitatively monitored the progress of pulmonary lesions in 6 days and timely made alert for suspected pneumonia, so that prompt medical isolation was taken. The patient was confirmed as COVID-19 case after nucleic acid test, for which the community transmission was prevented timely. The roles of DL-assisted diagnosis in helping radiologists screening suspected COVID cases were discussed.

Key words: coronavirus disease 2019, imported cases, computed tomography, deep learning, diagnosis
