The purpose of this work is to fuse two recently introduced concepts, namely Fourier decomposition (FD) MRI and ultra-fast steady-state free precession (ufSSFP) pulse sequence for improved lung imaging in the clinical setting. We compared to the standard implementation of the FD MRI technique with the newly adapted ufSSFP sequence in healthy volunteers at 1.5T. The ufSSFP performed beneficially over bSSFP in terms of signal intensity and banding artifacts, which can be used to either increase resolution or overall image quality for ventilation- and perfusion-weighted FD images.
