Caption
Representative coronal images obtained in an 82-year-old male patient with persisting shortness of breath 1 month after COVID-19 infection. Circles indicate pathology. The virtual noncontrast-enhanced images at (A) inspiration, (B) warped inspiration, and (C) expiration show areas of ground-glass opacifications in the right upper lobe, as well as emphysema in the left lung. The perfusion image (E) and the late enhancement image (F) show corresponding high values with ground-glass opacifications in the affected areas of the lung. (D) The ventilation image is heterogeneous, with areas of low to no ventilation in areas of emphysema, normal ventilation in healthy areas, and increased ventilation (ie, collapse) in the ground-glass opacifications. Exemplary measurements with region of interest in the right upper lobe are as follows: ventilation, 0.61; perfusion, 18% of vessel contrast; and late enhancement, 79% of vessel contrast.
