Oblique sagittal (a) and coronal (b) T2-weighted Dixon fat suppression MR images demonstrate enlargement and signal hyperintensity (arrows) of the common peroneal nerve at the level of the fibular head. (c) There is subtly increased T2-weighted signal intensity of the tibialis anterior muscle (outlined) compared with normal regional muscles. (d) T2 maps of the same calf musculature, where region of interest (ROI) 1 exhibits a normal T2 value of the unaffected peroneal musculature (38.2 ± 1.5 ms) while ROI 2 demonstrates T2 prolongation of the anterior tibialis (49.8 ± 1.9 ms), confirming suspected denervation.
