This research demonstrates the feasibility for accelerated acquisitions of whole-body (WB) multiple fast field echo protocols on a 3 Tesla scanner for fat-water MRI with a custom tabletop that allows a single 16-channel surface coil array to be used at every table position in a multiple station data collection strategy. The acceleration afforded by the strategy enables the collection of a high number of echoes in a reasonable acquisition time. The additional echoes enable WB quantitative fat-fraction mapping including R2* estimation.
