The utility of motion compensation diffusion-sensitized driven-equilibrium (MC-DSDE) for diffusion-weighted nerve sheath imaging (DW-NSI) from the C1 nerve to the T1 nerve was assessed and compared to EPI-DWI and conventional DSDE sequences, in human volunteers, at 3.0T. MC-DSDS was apparently superior to the other sequences, with less distortion and more smoothness, making it an appropriate method for DW-NSI.
