In this work we present a method to assess lung ventilation in 3D by combining Self-gated Non-Contrast-enhanced Functional Lung MRI (SENCEFUL) with an ultra-short echo time (UTE) acquisition and a 3D image registration technique. Ventilation weighted maps were generated and the quantitative ventilation value for a healthy volunteer was assessed. Lung ventilation and image quality were compared between the new UTE-SENCEFUL and the standard 2D-SENCEFUL methods. UTE-SENCEFUL was able to present a 3D reconstruction of the breathing cycle, 3D ventilation weighted maps with high resolution and quantitative ventilation values in agreement with the literature.
