Representative PREFUL and F-19 MRI results at baseline and three months of a male responder (age: 47). First row: PREFUL ventilation images; Second row: Ventilation defect percentage (VDP) maps; Third row: Flow-volume loop (FVL) maps. VDP changed from 54% to 23% and the FVL score over the whole lung increased from 88% to 98%. Fourth and fifth rows: second breath-hold F-19 ventilation with corresponding VDP map; sixth and seventh rows: sixth breath-hold F-19 ventilation with corresponding VDP map. Second VDP decreased from 26% to 10% and 6th VDP from 16% to 3%.
