Gradient echo images in the abdomen acquired at 3 T (a) and 1.5 T (b) with TR/TE = 180 ms/4.2 ms and a readout bandwidth of 65 Hz pixel-1. This results in a water/fat chemical shift in the frequency encoding direction (arrows) of 6.8 pixels at 3 T and 3.4 pixels at 1.5 T. TE, echo time; TR, repetition time.
