Respiratory-resolved and corrected 3D $$$\Delta B0$$$ mapping for 3D fat-water separated cardiac magnetic resonance imaging at ultra high fields is presented.
Fig.4: Resulting in vivo fat-water and fat fraction ($$$\text{FF}$$$) images of a coronal slice are shown for non-respiratory, non-cardiac resolved (NRR) and respiratory motion-corrected, cardiac binned (MOCO) reconstruction. The latter is shown in the end-diastolic phase. The red arrows indicating a blood flow artifact visible in NRR and reduced in MOCO. Line plot position is indicated by the dotted lines (I) and (II) with increased $$$\text{FF}$$$ for MOCO up to $$$24\%$$$ and reduced blood flow artifacts by the factor of 2 compared with NRR.
Fig.5: Fat-water and fat fraction ($$$\text{FF}$$$) images for 3 orthogonal views are shown for all 10 volunteers.
