A T1-weighted oxygen-enhanced Twisted Projection Imaging sequence was used to assess several functional lung parameters in 3D during free breathing. Retrospective DC-gating to expiration and inspiration enables the assessment of changes in T2* and T1 due to increased concentration of oxygen in the breathing gas for each respiratory state as well as changes in spin density at different breathing states.
