The aim of this work was to validate an automated scoring system of regional perfusion defects for data acquired by using a non-contrast-enhanced technique of Fourier decomposition 1H MRI (FD-MRI) in a group of cystic fibrosis (CF) patients. This work proves that automated assessment of regional perfusion defects in CF patients with FD-MRI is feasible and comparable to visual scoring. This diagnostic method could be well suited for reproducible and reader independent detection of early functional impairment and noninvasive monitoring of therapy response.
