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.
