Diffusion-weighted MR neurography of the sacral plexus with unidirectional motion probing gradients

BACKGROUND: This technical note introduces diffusion-weighted (DW) MR neurography (MRN) of the sacral plexus with unidirectional motion probing gradients (MPGs). METHODS: This is compared with DW MRN with three-directional and six-directional MPGs. RESULTS AND CONCLUSION: This paper indicates that DW MRN of the sacral plexus should be performed with unidirectional MPGs.
