Figure 3:

129Xe MRI ventilation scans 3 months (top) and 15 months (bottom) after COVID-19 infection in a 68-year-old woman who was hospitalized for 9 days during acute infection. Coronal 129Xe MRI scans show lung sections (cyan), with arrows indicating MRI ventilation abnormalities that improved at the 15-month follow-up. At 3 and 15 months, the forced expiratory volume in 1st second of expiration percent predicted was 84% and 100%, diffusing capacity of lung for carbon monoxide percent predicted was 81% and 91%, St George Respiratory Questionnaire score was 59 and 0, and ventilation defect percent was 2% and 0%, respectively.
