Inoue Y, et al. - The objective of this study is to evaluate the feasibility of T1-weighted 2-dimensional spoiled gradient-recalled (2D SPGR) acquisition in steady-state imaging of the liver with various respiratory navigator gating techniques. Navigator-gating techniques improved 2D SPGR images of the liver acquired amid free-breathing, proposing feasibility and beneficial impacts, although navigator-based images were still inferior to breath-hold images.
