Multi-Echo Gradient Echo phase measurements are important in various MR applications. Bipolar acquisitions of the MEGE echoes in a given TR allow for shorter inter-echo spacing and higher SNR efficiency than monopolar acquisitions, but introduce an unknown spatially varying phase between even and odd echoes. We propose here a strategy for reconstructing the underlying phase, as acquired with an array of receive coils using bipolar echoes, without requiring a reference scan. Our method separates the phase due to the underlying physiology from the phase offsets of the receive coils and the even-odd echoes, using a unifying Maximum-Likelihood framework.
