Therefore, we present a preliminary report on the chest radiographic and CT findings of COVID-19 pneumonia in Korea.Īll CT examinations were performed using a multi-detector CT scanner with 64 or more channels (Somatom Definition, Somatom Definition AS+, or Somatom Force, Siemens Healthineers, Erlangen, Germany). The current publications on this topic are exclusively from China, and it remains unknown how COVID-19 pneumonia appears on chest radiographs and CT images of patients outside China. The discrepancy in the death rate between China and other countries might be due to differences in the disease manifestation of COVID-19 pneumonia or in other countries' capacity to manage a limited number of cases, in contrast to the overwhelming numbers of cases in China.Įarly radiologic investigations consistently reported that the typical computed tomography (CT) findings of COVID-19 pneumonia were bilateral ground-glass opacities (GGOs) and consolidation with a peripheral and posterior lung distribution ( 4, 5, 6). Deaths have almost exclusively occurred in China (1666 patients 3.3%), rather than outside China (3 patients 0.4%). As of February 16, there were 29 COVID-19 patients in Korea, placing Korea in fifth place internationally in terms of the number of COVID-19 patients, after China, Singapore (72 patients), Japan (53 patients), and Thailand (34 patients). The first COVID-19 patient was identified in South Korea (hereafter, Korea) on January 20, 2020. As of February 16, 2020, COVID-19 infections had been confirmed in 51857 patients globally, including 51174 patients in China and 683 patients outside China ( 3). Human-to-human transmission of COVID-19 was confirmed to be possible ( 2), and COVID-19 rapidly spread throughout China and to other countries. A prompt investigation confirmed that the 2019 novel coronavirus disease (COVID-19 temporarily termed as 2019-nCoV) was responsible ( 1).
