目的：研究韩国2019年新型冠状病毒病(新冠肺炎)肺炎的胸部X线和CT表现。材料和方法：作为韩国胸部放射学会协调的多机构合作的一部分，我们收集了9例新冠肺炎感染患者的胸部X线和CT扫描。分析新冠肺炎肺炎患者基线的X线和CT表现。结果：9例患者中有3例(33.3%)胸部平片发现肺实质异常，且多为周围实变。胸部CT显示9例患者中有8例为双侧受累，另1例为单叶晕征。总共发现77个肺部病变，包括斑片状病变(39%)、大融合病变(13%)和小结节状病变(48%)。周围肺野受累78%，后肺野受累67%。典型的病变边界不清，由混合性毛玻璃样阴影和实变或纯毛玻璃样阴影组成。斑片状至融合性病变主要分布在肺下叶(p=0.040)和沿胸膜(p<；0.001)，而结节状病变主要沿支气管血管束分布(p=0.006)。结论：韩国新冠肺炎肺炎主要表现为单纯至混合性磨玻璃样阴影，双肺周围后肺呈片状至融合状或结节状。相当一部分新冠肺炎肺炎患者的胸片正常。
Objective: This study presents a preliminary report on the chest radiographic and computed tomography (CT) findings of the 2019 novel coronavirus disease (COVID-19) pneumonia in Korea.Materials and Methods: As part of a multi-institutional collaboration coordinated by the Korean Society of Thoracic Radiology, we collected nine patients with COVID-19 infections who had undergone chest radiography and CT scans. We analyzed the radiographic and CT findings of COVID-19 pneumonia at baseline. Fisher's exact test was used to compare CT findings depending on the shape of pulmonary lesions.Results: Three of the nine patients (33.3%) had parenchymal abnormalities detected by chest radiography, and most of the abnormalities were peripheral consolidations. Chest CT images showed bilateral involvement in eight of the nine patients, and a unilobar reversed halo sign in the other patient. In total, 77 pulmonary lesions were found, including patchy lesions (39%), large confluent lesions (13%), and small nodular lesions (48%). The peripheral and posterior lung fields were involved in 78% and 67% of the lesions, respectively. The lesions were typically ill-defined and were composed of mixed ground-glass opacities and consolidation or pure ground-glass opacities. Patchy to confluent lesions were primarily distributed in the lower lobes (p = 0.040) and along the pleura (p < 0.001), whereas nodular lesions were primarily distributed along the bronchovascular bundles (p = 0.006).Conclusion: COVID-19 pneumonia in Korea primarily manifested as pure to mixed ground-glass opacities with a patchy to confluent or nodular shape in the bilateral peripheral posterior lungs. A considerable proportion of patients with COVID-19 pneumonia had normal chest radiographs.
