This study showed a new scheme for MR neurography of the wrist by using phase-cycled diffusion-sensitized driven equilibrium (pcDSDE) technique for achieving high-resolution MR neurography in the wrist. pcDSDE sequence clearly showed both anatomies and courses of median nerve, ulnar nerve and their branches. Furthermore, this sequence could offer gself-fusionh images simultaneously by using two types of reconstructed images (neurography images and anatomical images). DSDE sequence has great potential to stably depict peripheral nerves in the extremities.
