Lung MRI is challenging due to the short T2* and respiratory and cardiac motion. In this study an UTE stack-of-stars sequence has been combined with tiny golden angle (tyGA SoS) for imaging of lung morphology (proton fraction, PF) and function (fractional ventilation, FV). Application of the techniques to smoker and non-smokers revealed significant differences in the PF thus indicating its sensitivity.
