A rapid multi-slice fat/water separated imaging protocol has been developed for mapping body fat with application to obesity studies. The method combines a 3-echo GRE acquisition and parallel imaging to scan the abdomen and chest in <30 sec. A recently developed joint estimation method for water/fat separation is able to perform robustly in the presence of large B0 field inhomogeneities.
