Liver magnetic resonance elastography (MRE) to this point has clinically relied on using breath holds to produce reliable artifact free images. Here we present initial work adapting recent advances in motion compensated abdominal imaging for use in MRE. Specifically, we take advantage of a golden angle radial sampling scheme combined with a self-navigation approach for motion correction to perform free breathing MRE of the liver. Resulting images show enhanced detail compared to the standard breath hold technique while producing comparable image stiffness values.
