Two gradient‐recalled lipid suppression sequences are proposed. A two‐excitation sequence cycles the TE interval between excitations to alter the lipid phase which is fol‐lowed by complex subtraction. A four‐excitation variant which improves the extent of lipid suppression by partially compensating for errors resulting from spin‐spin relaxation and B o inhomogeneities is outlined. © 1988 Academic Press, Inc.
