Summary of Recommendations for Imaging

Main recommendations

Imaging is not routinely indicated as a screening test for COVID-19 in asymptomatic individuals

Imaging is not indicated for patients with mild features of COVID-19 unless they are at risk for disease progression (scenario 1)

Imaging is indicated for patients with moderate to severe features of COVID-19 regardless of COVID-19 test results (scenarios 2 and 3)

Imaging is indicated for patients with COVID-19 and evidence of worsening respiratory status (scenarios 1, 2, and 3)

In a resource-constrained environment where access to CT is limited, chest radiography may be preferred for patients with COVID-19 unless features of respiratory worsening warrant the use of CT (scenarios 2 and 3)

Additional recommendations

Daily chest radiographs are NOT indicated in stable intubated patients with COVID-19

CT is indicated in patients with functional impairment and/or hypoxemia after recovery from COVID-19

COVID-19 testing is indicated in patients incidentally found to have findings suggestive of COVID-19 on a CT scan
