Abstract EN
Introduction.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly contagious disease, and its first outbreak was reported in Wuhan, China.
A coronavirus disease (COVID-19) causes severe respiratory distress (ARDS).
Due to the primary involvement of the respiratory system, chest CT is strongly recommended in suspected COVID-19 cases, for both initial evaluation and follow-up.
Objective.
The aim of this review was to systematically analyze the existing literature on CT imaging features of patients with COVID-19 pneumonia.
Methods.
A systematic search was conducted on PubMed, Embase, Cochrane Library, Open Access Journals (OAJ), and Google Scholar databases until April 15, 2020.
All articles with a report of CT findings in COVID-19 patients published in English from the onset of COVID-19 outbreak to April 20, 2020, were included in the study.
Result.
From a total of 5041 COVID-19-infected patients, about 98% (4940/5041) had abnormalities in chest CT, while about 2% have normal chest CT findings.
Among COVID-19 patients with abnormal chest CT findings, 80% (3952/4940) had bilateral lung involvement.
Ground-glass opacity (GGO) and mixed GGO with consolidation were observed in 2482 (65%) and 768 (18%) patients, respectively.
Consolidations were detected in 1259 (22%) patients with COVID-19 pneumonia.
CT images also showed interlobular septal thickening in about 691 (27%) patients.
Conclusion.
Frequent involvement of bilateral lung infections, ground-glass opacities, consolidation, crazy paving pattern, air bronchogram signs, and intralobular septal thickening were common CT imaging features of patients with COVID-19 pneumonia.
