MRI has recently emerged as a potential clinical tool that can produce high resolution images of structural changes in the lung thanks to the use of ultrashort TE readouts without the ionizing radiation of CT scans [3-6]. Thanks to this developments, pediatric cystic fibrosis (CF) patients can undergo routine monitoring with CT like quality [1]. In this study we investigate three different MRI sequences (UTE, ZTE3D vnav and ZTE 4D). In general, all sequences perform reasonably well though ZTE3D vnav seems to provide the best performance for CF monitoring.
