A general data processing formalism is presented which can be applied to the signal intensities of successive echoes of a multiple‐echo data set in order to null those species for which the signal decay function is exponential. If asymmetric echo times are introduced into the multiple‐echo sequence then chemical shift images akin to those obtained from the magnitude Dixon method can be obtained in half the data acquisition time. © 1991 Academic Press.
