The MR fingerprinting (MRF) has recently been introduced to generate various quantitative parameter maps in a single image acquisition. In this study we extend MRF to apply it to fat/water separation. In addition to acquiring parameter maps of T1 and T2, fat and water fraction maps were created with a dedicated MRF pulse sequence and an orthogonal matching pursuit algorithm with 3 iterations. In a phantom experiment the fat/water separations shows a good agreement with data from an MR spectroscopic method.
