✦ Synopsis
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 followed 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 B0 inhomogeneities is outlined.

## Abstract Selective suppression of silicone or fat with chemical shift–selective (CHESS) pulses is difficult because of the small chemical shift difference between the primary lipid signal and the primary silicone signal at 1.5 T. Differentiation of these chemically distinct species is, however,
## Abstract We demonstrate that magnetization transfer contrast can be used to improve the diagnostic utility of fat‐suppressed steady‐state three‐dimensional gradient‐recalled images. Fat suppression is achieved using a “jump‐return” pair of contiguous shaped pulses. No time interval exists betwee
