Single shot DW-EPI suffers from geometric distortions
and is limited in resolution. A preparation phase
(Diffusion sensitized driven equilibrium (DSDE)) which
restores the diffusion weighted magnetization along the
longitudinal axis allows for additional readout
strategies such as TFE. DSDE-TFE can produce distortion
free, high resolution diffusion weighted images, also in
otherwise difficult areas to perform diffusion weighted
imaging such as the neck.
