COVID-19 transmits mainly through respiratory droplets and close contacts, causing cluster infections. The symptoms are dominantly fever, fatigue, and dry cough, and can be complicated with tiredness, sore throat, and headache. A few patients have symptoms such as stuffy nose, runny nose, and diarrhea. The severe disease can progress rapidly into the acute respiratory distress syndrome (ARDS). Reverse transcription polymerase chain reaction (RT-PCR) and Next-generation sequencing (NGS) are the gold standard for diagnosing COVID-19. Chest imaging is used for cross validation. Chest CT is highly recommended as the preferred imaging diagnosis method for COVID-19 due to its high density and high spatial resolution. The common CT manifestation of COVID-19 includes multiple segmental ground glass opacities (GGOs) distributed dominantly in extrapulmonary\/subpleural zones and along bronchovascular bundles with crazy paving sign and interlobular septal thickening and consolidation. Pleural effusion or mediastinal lymphadenopathy is rarely seen. In CT imaging, COVID-19 manifests differently in its various stages including the early stage, the progression (consolidation) stage, and the absorption stage. In its early stage, it manifests as scattered flaky GGOs in various sizes, dominated by peripheral pulmonary zone\/subpleural distributions. In the progression state, GGOs increase in number and\/or size, and lung consolidations may become visible. The main manifestation in the absorption stage is interstitial change of both lungs, such as fibrous cords and reticular opacities. Differentiation between COVID-19 pneumonia and other viral pneumonias are also analyzed. Thus, CT examination can help reduce false negatives of nucleic acid tests.<\/jats:p>","DOI":"10.3233\/xst-200687","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T14:03:11Z","timestamp":1591711391000},"page":"391-404","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Clinical and radiological features of novel coronavirus pneumonia"],"prefix":"10.1177","volume":"28","author":[{"given":"Qiuting","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Medical Imaging, Shenzhen Center for Chronic Disease Control, Guangdong Shenzhen 518020, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yibo","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, The Fourth People\u2019s Hospital of Nanning, Guangxi Nanning 530023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fleming","family":"Lure","sequence":"additional","affiliation":[{"name":"MS Technologies, 10110 Molecular Dr., Suite 305, Rockville, MD 20850, USA"},{"name":"Shenzhen Zhiying Medical Co., Ltd, Guangdong Shenzhen 518020, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Jaeger","sequence":"additional","affiliation":[{"name":"National Library of Medicine, National Institutes of Health, 8600 Rockville Pike, Bethesda, MD 20894, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Puxuan","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Shenzhen Center for Chronic Disease Control, Guangdong Shenzhen 518020, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,6]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(20)30185-9"},{"key":"ref002","unstructured":"National Health Commission.
