Free-breathing phase-resolved functional lung (PREFUL) low-field MRI at 0.55T with calculated parameters at an axial plane after automatic registration to a mid-expiration position and lung parenchyma segmentation. From left to right, representative color-coded images of functional show ventilation defects (VDP, blue), perfusion defects (QDP, red), ventilation/perfusion (V/Q match, green), ventilation/perfusion defects (V/Q defect, purple) in a healthy control (upper row, 7-year-old male), a participant recovered from COVID-19 (middle row, 10-year-old male) and a participant with long COVID (15-year-old male).
