3D Ultrashort TE (UTE) MRI was carried out in vivo on mice without respiratory restrictions. The importance of experimentally measuring k-space trajectories for image reconstruction was studied. Additionally, retrospectively respiratory gating the 3D data set allowed for images at two distinct respiratory phases to be reconstructed, providing valuable physiological information regarding pulmonary physiology.
