State-of-the-art structural pulmonary MRI of neonatal intensive care unit patients has previously been performed using 3D radial UTE. Performance is high yet scan times can be 15 minutes or more due to the low sampling efficiency of radial trajectories. Here we explore FLORET UTE in this application and demonstrate comparable image quality to the state-of-the-art in approximately 25% of the scan time. Lung parenchymal SNR is maintained, and the spiral trajectory provides a higher parenchymal signal relative to muscle. Shorter scan times reduce the opportunity for bulk motion and risk to this sensitive population.
