Annotated gradient refocused echo MRI (a) showing the location of an N = 64 NEX STEAM data set acquired from a human leg with conventional averaging (b, lower spectrum) and constructive averaging (b, upper spectrum) of the identical data set acquired at 1.5 Tesla. In this case, the leg was tremored continuously during the acquisition. Constructive averaging based on phasing either the lipid resonance (–CH2–) or the incompletely suppressed water resonance yielded the same result—about a fivefold increase in SNR. The experimental range of phase variation is 334°, and σφ = 88°.
