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.
