Dual-repetition gradient-echo sequences are currently not widely used for Dixon imaging, because shorter scan times and better signal-to-noise ratios are usually achieved with their dual-echo counterparts. In this work, the efficiency of dual-repetition gradient-echo sequences is optimized by introducing partial echo sampling to extend the acquisition windows and by applying compressed sensing to reduce scan times. On the example of knee imaging, this is shown to enable high-resolution water-fat imaging with good image quality in reasonable scan times.
