Background: Coronaviruses are non-segmented enveloped positive-sense single-strand
RNA viruses, and COVID-19 is the seventh known coronavirus, infecting humans.
Objective: As the COVID-19 continued to spread the world wildly, every radiologist or clinician
needs to be familiar with its imaging findings.
Methods: In this study, we reviewed available studies to provide a comprehensive statement on
COVID-19 imaging findings.
Results: Ground-glass opacities, linear opacities, interlobular septal thickening, consolidation, and
Crazy-paving patterns are the most frequent findings in computed tomography (CT) of lungs in
patients with COVID-19 pneumonia, which are mostly bilateral, multifocal, and peripheral. Staff
needs to follow some rules to reduce infection transmission.
Conclusion: COVID-19 pneumonia is a new global concern that has many unknown features. In this
article, the radiologic characteristics of COVID-19 pneumonia are discussed. We also discussed
appropriate protective measures that the radiology team should be aware of.
