DNP of 129Xe has the potential to be used for clinical application in MR imaging of the lung parenchyma and structure. Achieving high polarization values are paramount to achieving this goal. Here we demonstrate the utility of pellet formation (on the mm scale) for substantial gains in DNP efficiency in the solid state.
