MR neurography for the crus is challenging because signals of the vessels and subcutaneous edema interrupt visualization of the nerve, and the water content of the nerve is small. Phase-cycling diffusion-sensitized driven-equilibrium (pcDSDE) can reduce signals of the neighboring structures including the vesssels, and visualize the nerves with diffusion contrast. pcDSDE was better than 3D-NerveVIEW for visualizing the tibial and sural nerves in the crus. The contrast ratio between the tibial nerve and neighboring muscle was significantly higher on pcDSDE than on 3D-NerveVIEW in both the proximal and distal crura.
