Number of echo sampling for optimal TE=0 estimation. (a) Standard deviation of the estimated initial phase (at TE=0) as a function of readout duration. (b) The optimal TE value collected for minimizing the standard deviation of phase estimate noise as a function of T2* variations. The plots show that the multiecho GRE sequence should acquire data up to approximately the T2* value of the object.
