When leaving the comfortable zone of the first OP/IP echos small adjustments in TE can make a huge difference for symmetrically sampled Dixon imaging. Fortunately on the fly compensation is relatively easy using a short single voxel spectroscopy scan and a model of the fat/water interference. The method is tested using the second OP and third IP echo, both In Vitro and in vivo.
