Deriving functional lung data by MRI is challenging, but initial studies have proven the applicability of multi-respiratory stage data for deriving fractional lung ventilation data. In this study a two-dimensional ultra-short TE protocol was used to acquire breathhold (expiration and inspiration) and free breathing date of the lung parenchyma. Lung proton density changes and respective fractional ventilation could be assessed with either techniques. Due to the shallow breathing, in the free-breathing approach differences resulted less pronounced as in the breathhold approach.
