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.
