The Fast Triple Echo Dixon fat-water separation technique is combined with QMAP, to obtain in a single sequence the relative signal fraction of each species, in addition to the T1, T2, and PD information provided by QMAP. The FSE sequence is modified by a replacing the standard readout pulse with a three-echo bipolar readout. The fat/water separation is first performed, and relaxation parameter fitting is then applied separately to the fat and water images. Not only is more information provided in this technique, but quantitation could potentially be improved in mixed voxel species.
