paper proposes an inversion-recovery spin-echo SNAPSHOT-FLASH
sequence for quantifying proton-density and T1 of the lung. It is shown
that T1 is reduced compared to the standard gradient-echo
sequence. Similar results have been previously reported for UTE sequences. In combination with an iterative algorithm that is similar to
MR-fingerprinting reconstructions, the feasibility of acquiring
quantitative maps of the entire lung with a resolution of 5 mm x 5 mm x 10 mm within 5.5 s is demonstrated.
