Existing two-point Dixon methods require at least one echo time being in phase. Thus, they restrict flexibility in the selection of protocol parameters and compromise scan efficiency. In this work, a novel two-point Dixon method is outlined that removes restrictions on the echo times. It is characterized in terms of noise propagation, and it is demonstrated to enable shorter scan times, higher spatial resolution, and increased signal-to-noise ratio in abdominal imaging in single breathholds.
