Figure 2 Axial view of diffusion tensor imaging (B, C) and T2 weighted image (A) from a patient in the AI group at baseline. The regions of interest of the tibial (red) and common peroneal (green) nerves at the level of the right knee were displayed. Color fractional anisotropy maps (B) and apparent diffusion coefficient maps (C) of the tibial nerve and common peroneal nerve at the popliteal fossa level are shown. The figure was created by the software Syngo.via (VB40 Siemens Healthineers, Germany).
