Caption

Images show exemplary coronal sections of phase-resolved functional lung MRI ventilation and perfusion maps in a 15-year-old female participant with post–COVID-19 condition (PCC) and in a sex- and age-matched healthy control participant. (A, B) Images show regional ventilation, with values of (A) 0.1 mL/mL in the participant with PCC and (B) 0.5 mL/mL in the healthy control participant. Regarding dynamic ventilation (C, D), images show the flow-volume loop correlation metric, with (C) the participant with PCC at 0.98 arbitrary units (au) and (D) the healthy control participant at 0.99 au. (E, F) Images show perfusion maps depicting a median quantified perfusion of 27 mL/min per 100 mL for the participant with PCC and 89 mL/min per 100 mL for the healthy control participant.
