Dorsal, medial, and ventral phase-resolved functional lung MRI perfusion maps show distinct perfusion phenotypes related to the severity of chronic fatigue assessed with the Bell score in three participants with post–COVID-19 condition and in a healthy control participant. The top row shows maps from a 17-year-old male healthy control participant with a median quantified perfusion of 81 mL/min per 100 mL. The second row from the top shows maps from a 17-year-old male participant with a Bell score of 90 and a quantified perfusion of 59 mL/min per 100 mL. The second row from the bottom shows maps from a 16-year-old female participant with a Bell score of 60 with a quantified perfusion of 48 mL/min per 100 mL. The bottom row shows maps from a 15-yearold male participant with a Bell score of 30 and a quantified perfusion of 32 mL/min per 100 mL.
