Tagging techniques such as SPAMM and CSPAMM have been useful for assessment of dynamic cardiac tissue deformation. Recent advances in ultra-short echo time (UTE) imaging have enable imaging of lung parenchyma. In this work, we evaluate the possibility of using spatial tags in conjunction with UTE imaging to assess regional ventilation and tissue stiffness with non-enhanced, endogenous contrast.
