Among the 139 patients with COVID-19 who were hospitalized in Yeungnam University Hopistal in Daegu, South Korea, 10 (7.2%) were asymptomatic. Their chest CT and radiographic findings were analyzed. <b><i>Results:<\/i><\/b> In the results, all patients (100%) had ground-glass opacity (GGO) on chest CT. Further, the GGO lesions were predominantly distributed peripherally and posteriorly in all patients. In 9 (90%) patients, the GGO lesions were combined with reticular opacity. Air bronchogram due to bronchiolectasis surrounded by GGO was observed in 8 patients (80%). Additionally, the lung lesions were dominant on the right side in all patients. <b><i>Conclusions:<\/i><\/b> In conclusion, considering our results that the lung is affected in asymptomatic patients, it will be necessary to extend the indications of COVID-19 testing for effective management of COVID-19 during the pandemic.<\/jats:p>","DOI":"10.1159\/000509334","type":"journal-article","created":{"date-parts":[[2020,9,7]],"date-time":"2020-09-07T17:00:31Z","timestamp":1599498031000},"page":"748-754","source":"Crossref","is-referenced-by-count":17,"title":["Chest Computed Tomography Findings in Asymptomatic Patients with COVID-19"],"prefix":"10.1159","volume":"99","author":[{"given":"Min\u00a0Cheol","family":"Chang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wonho","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Hur","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7724-4682","authenticated-orcid":false,"given":"Donghwi","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2020,9,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s12098-020-03263-6"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S2213-2600(20)30076-X"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2020.03.020"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm6913e1"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.2807\/1560-7917.ES.2020.25.10.2000180"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.m1375"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.26041"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2008457"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2020.0132"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2462070712"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.20.22975"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-020-06731-x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-020-06801-0"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1007\/s11604-020-00945-1"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmi.2020.03.024"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(20)30198-5"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.acra.2020.03.002"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2020200642"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/509334","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/509334","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T11:46:11Z","timestamp":1745408771000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000509334"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020]]},"references-count":18,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2020,12,8]]},"published-print":{"date-parts":[[2020,12,9]]}},"URL":"https:\/\/doi.org\/10.1159\/000509334","archive":["Portico"],"relation":{"has-preprint":[{"id-type":"doi","id":"10.1101\/2020.05.09.20096370","asserted-by":"object"}]},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"value":"0025-7931","type":"print"},{"value":"1423-0356","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020]]}}}
