Multi-echo gradient-echo Dixon based on the chemical shift method is currently the standard for non-invasive in vivo quantification of the liver fat but requires breath-holding. In young children or sick patients this is often challenging or not feasible. Despite recent attempts using different free-breathing approaches to mitigate patient motions, these are not widely available or routinely used. In this work we employ the multi-echo Dixon sequence with 3D pseudo-golden angle radial stack-of-stars readout for free-breathing liver fat assessment and report our initial results in children and adults at 3T and 1.5T with phantom validation and comparison to the standard method.
