Figure 1.

Diagram illustrates the first of three clinical scenarios presented to the panel with final recommendations. Mild features refer to absence of significant pulmonary dysfunction or damage. Pretest probability is based on background prevalence of disease and may be further modified by individual’s exposure risk. The absence of resource constraints corresponds to sufficient availability of personnel, personal protective equipment, coronavirus disease 2019 (COVID-19) testing, hospital beds, and/or ventilators with the need to rapidly triage patients. Numbers in blue circles indicate key questions referenced in the text and presented in Figure 4. Contextual detail and considerations for imaging with chest radiography versus CT are presented in the text. Although not covered by this scenario and not shown in the figure, in the presence of substantial resources constraints, there is no role for imaging of patients with mild features of COVID-19. ∗ = Clinical judgment should dictate the use of imaging through consideration of patient risk factors and local resources. Mod = moderate; Neg = negative; Pos = positive.
