Abstract The coronavirus disease 2019 (COVID-19) that occurred in Wuhan, Hubei Province, China, has been declared a public health emergency of international concern and a pandemic by the World Health Organization. The Chinese government has temporarily taken strong response measures and effective procedures to stop the further expansion and development of the epidemic. It is important for clinicians to screen, diagnose, and monitor COVID-19. Keywords COVID-19 · Computed tomography · Imaging · SARS-CoV-2
Introduction In December 2019, an outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection caused the coronavirus disease 2019 (COVID-19) that occurred in Wuhan, Hubei Province, China and spread worldwide in the next few weeks [1, 2]. Human-to-human transmission of COVID-19 was confirmed by droplets, contact and fomites [3, 4]. The researches have suggested that COVID19 is more contagious than both severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) [1, 5–7]. On January 30, 2020, the International Health Regulations Emergency Committee of the WHO declared that the epidemic caused by the new coronavirus had become a “public health emergency of international concern” (PHEIC) [8].

Subsequently, the number of infections in China’s neighboring countries (South Korea, Japan) increased exponentially, which caused panic among local people, and the number of new cases reported outside China exceeded the number of new cases in China for the first time on February 26, 2020 [9]. As of on March 16, 2020, there were 81,077 confirmed infections and 3218 deaths in China, and 86,434 confirmed cases with 3388 deaths were reported in 151 countries (Italy, Iran, South Korea, Spain, Germany, were the top five countries) [10]. Therefore, early diagnosis, treatment, and intervention are particularly important. Although viral nucleic acid detection using real-time polymerase chain reaction (RT-PCR) remains the diagnostic criteria, the sensitivity of an initial chest CT was greater than the first RT-PCR [11, 12]. Chest CT can screen patients infected with COVID-19. However, it is worth considering how to evaluate the value and effective use of chest CT in COVID-19. We share three
