Improvement in the left base can be seen from day 120 to day 360. b Values are median (25th–75th percentile) of 5 patients at each time point. Statistical analysis of lung perfusion, showing significant differences mainly in the base of the right lungs from day 30 to day 360 as compared with baseline. RL, right lung; LL, left lung
