The performance of water and fat separation with conventional 3-point Dixon methods is limited by the phase unwrapping algorithm and tissue connectivity. Recently an IDEAL algorithm was proposed to generate robust water and fat separation. In this work we propose an asymmetrical radial GRASE technique combined with the IDEAL algorithm to achieve better time efficiency, robust water and fat separation, and high noise performance. With this technique, one complete data set can be acquired in a breath hold which makes it attractive for abdominal or cardiac imaging.
