Silicone-specific imaging can be performed using
various combinations of selective inversion, selective saturation, and Dixon
methods. In this work, we propose and demonstrate a new silicone-specific
imaging method with a unipolar flexible fast spin echo triple echo Dixon pulse
sequence. The method treats the water
and fat signals as a single component by acquiring images only when water and
fat are in-phase, and to use Dixon processing with flexible echo times to
separate the remaining silicone signal. Among its many advantages, the method
maintains high SNR and scan efficiency, is insensitive to field inhomogeneity,
and is not subject to chemical shift misregistration.
