- Figure 1
Portable chest radiographs of a patients with COVID-19 demonstrating classic bilateral, multifocal peripheral airspace opacities in the mid-lower-lung zones.
- Figure 2
Portable chest radiographs of patients with COVID-19 demonstrating atypical features of diffuse bilateral interstitial changes (A) and unilateral consolidation (B).
- Figure 3
Serial chest radiographs in a 53-year-old woman with COVID-19 demonstrate peripheral opacities on the day of onset of symptoms (A) with rapid worsening by day 3 (B). The patient was subsequently intubated, with the peak severity of parenchymal findings on day 11 (C).

(Left) Setup for obtaining chest radiographs through the glass wall of the room of a patient with suspected or confirmed COVID-19. (Middle) A radiograph obtained in the conventional manner. (Right) A radiograph obtained through the glass.
- Figure 5
Typical computed tomographic features of COVID-19. Unenhanced axial images of the lungs of 4 different patients with COVID-19 demonstrate bilateral, multifocal, peripheral ground-glass opacities, and consolidation, most with rounded morphology. “Crazy paving” (ground-glass opacities with superimposed interlobular septal thickening and intralobular lines) is seen in (C) (white arrow).

CT scans in a 73-year-old man with COVID-19 demonstrate resolution of subpleural consolidation with residual reticular and fibrotic changes.

CT images of 2 different patients with COVID-19 demonstrating pulmonary embolism.
Tables
Early stage (0–2 days) Approximately 50% of patients have negative chest CT The remaining have ground-glass opacities (44%) and consolidation (17%), more often unilateral The less pulmonary consolidation identified on CT, the greater the probability of initial negative reverse transcriptase polymerase chain reaction results11 Intermediate stage (3–5 days) 9% of patients have negative chest CT 88% have ground-glass opacities with or without crazy paving (a sign of progression or peak stage), and 55% have consolidation (bilateral in 76%, peripheral in distribution in 64% with rounded morphology)12 Late phase (6–12 days) Most patients have positive CT findings Progressive consolidation, evolving linear consolidation, and organizing pneumonia Reverse-halo appearance (a sign of healing or evolving lesion)12 Ground-glass opacities in 88% with or without crazy paving Severe phase Massive pulmonary consolidation and “white lungs” Recovery phase Parenchymal abnormalities resolve with residual linear opacities (Figure 6) Based on information from references 5 and 11–14.
