Motion artifact suppression is a major challenge in
abdominal magnetic resonance imaging, and particularly
in quantitative imaging. Here, a new technique is
introduced, where 3D high-resolution abdominal T
1
maps
are obtained during free-breathing by combining
inversion-recovery Look-Locker method, respiratory
self-navigation, and 3D golden angle through-time spiral
GRAPPA reconstruction. T
1
values
from different tissues are in excellent agreement with
breath-hold data and literature. This technique may be
beneficial for those who cannot hold their breath during
MR acquisition or need a larger spatial coverage or
higher spatial resolution.
