Oxygen-enhanced MRI of the lung is a promising tool for the development of early disease markers or long-term monitoring of disease activity. However, so far few data exist about the reliability of this method in a clinical setting. Healthy individuals were scanned two times using two different gas delivery methods usually available in clinical settings. A full covering face mask with a half-closed gas delivery system showed highly reproducible T1 values and oxygen transfer function. Furthermore, using this mask lower variability between healthy individuals was seen compared to a loose-fit mask.
