Authors’ conclusions: radiological findings in children with COVID-19 are often normal or mild, with unilateral involvement, ground-glass pattern, and affecting lower lobes. Chest CT should be reserved for severe cases or to identify other diagnoses.
Reviewers’ commentary: performing chest CT imaging should be limited to severe cases, if it is going to lead to a change in clinical attitude. Although the most frequent changes are unilateral involvement of lower lobes and ground glass pattern, it remains to be defined what type of test to perform, and which images may be indicative of a worse prognosis in pediatric population. The risk of radiation outweighs the benefits of chest CT in not severe cases.
