✦ Synopsis

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, an important clinical task in assessing implant rupture and silicone migration in breast tissue. A method uniquely suited for silicone‐fat differentiation with fast spin‐echo (FSE) sequences is reported. It is based on the dependence of fat signal on echo spacing in FSE imaging and results show that it may provide a clinically robust method for silicone‐fat differentiation in magnetic resonance imaging of the breast.

## Abstract It is well known that when compared to conventional spin‐echo (CSE) imaging for equivalent effective echo times, fast spin‐echo (FSE) imaging experiments yield higher signal intensities for coupled spin systems, such as that for lipid. One hypothesis put forth for this phenomenon is the

## Abstract A method for suppressing fat in fast spin‐echo imaging with the three‐point Dixon technique is described. The method differs from the three‐point Dixon method used in conventional spin‐echo imaging in that the readout gradient instead of a radio‐frequency pulse is shifted. This method p
