MRI measurements and outcomes. a, b Examples of manual image segmentation in the right and left lung at expiration and inspiration in an healthy control. c Steps of the automatic algorithm to define reference points to calculate the different outcome measures. d and e Thorax- and diaphragm-related outcomes. The grey lines depict the outlines of the lung in consecutive images from end expiration to end-inspiration. The red point indicates the anterior corner of the diaphragm and the blue point the posterior corner of the diaphragm. The green points indicate displacement of the lung apex and diaphragm apex. Purple arrows and purple areas indicate the outcome measurements
