Pulmonary ventilation assessed by Fourier Decomposition (FD) is limited by its 2D acquisition and does not consider dynamics of ventilation. In this work, a method to assess dynamic lung ventilation in 3D using self-gating and phase-resolved functional lung imaging (PREFUL) is presented. The full respiratory cycle was reconstructed and dynamic regional ventilation (RV) maps were generated. Mean slice correlation and anterior-posterior gradient of ventilation values were compared between the 3D and the 2D PREFUL approaches. 3D PREFUL imaging was able to reconstruct dynamic imaging of the respiratory cycle, generate dynamic RV maps and provide good agreement with the 2D approach.
