(A) Example iNAVs for 2 subjects, showing water, fat, in‐phase and out‐of‐phase navigators, with the corresponding template used for motion tracking indicated in red. In both cases, water/fat separation results in a clear depiction of subcutaneous fat in the fat iNAVs. Reduced spatial resolution prevents the visualization of smaller fatty structures. (B) FH and RL motion estimation from water, fat, in‐phase and out‐of‐phase iNAVs for the same subjects. In both cases, FH estimation is consistent across different iNAVs, while differences are apparent in RL estimation. In particular for subject 2, fat iNAVs result in unrealistic RL motion estimation (>12 mm, green arrows)
