A simultaneous, free-breathing water/fat separation
and T1, T2 quantification method was proposed. Dual TR (in-phase and out-phase
TR) and varying sinusoidal flip angle was used with FISP acquisition. For
motion robustness, random rotating golden angle trajectories were applied. T1,
T2 and Δφfat of fat were pre-determined using
the fat dominant region mask, then water/fat signal combined dictionary was
generated. The results show that the water/fraction maps from the proposed
method were in good agreement with conventional breath-hold results. Furthermore,
measured T1, T2 values were in good agreement with the values from the previous
research.
