Spatially varying fat-water separation by 2DRF is demonstrated in b-ssfp phantom images at 3T (TE=3ms, TR=6ms, flip angle=45°, FOV=20cm, matrix size=128×128, slice thickness=8mm). (a) A reference image produced by the product sequence using a 1D SINC pulse; (b) The spatial shift of excitation patterns in vegetable oil from water can readily be observed with FOE=0.25FOV; (c) the spatially varying fat-water excitation with the shift factor Rshift=0, (d) the excitation with Rshift=0.25, (e) the excitation with Rshift=0.5 and (f) the excitation with Rshift=0.75 are shown. Fig. (c–f) were produced using a 5×560μs 2DRF pulse and FOE=2FOV, corresponding to the scenarios described with FOV1 to FOV4 in Fig. 2d.
