In Vivo MR Microneurography of the Tibial and Common Peroneal Nerves

Figure 1

3D SPGR FS, FOV 5 cm. Axial sections at the posteromedial aspect of the tibia, above the medial malleolus. The tibial nerve is visualized (large arrow) with the typical fascicular pattern. The neurovascular bundle is seen at the posteromedial aspect of the tibia. Sequential images at high resolution demonstrate the medial calcaneal nerve dividing into anterior and posterior branches, providing sensory innervation to the plantar aspect of the heel (small arrows).
