Comparison of MR findings of acute traumatic peripheral nerve injury and acute compressive neuropathy in a rat model
Fig 6
MR images of a rat with compression injury 10 days after the surgery.
In the oblique coronal (A, B) and axial (C, D) fat-suppressed T2-weighted images, the injured nerve is diffusely thickened and distinctly hyperintense, suggesting grade 3 change. This change in the nerve is obvious at the proximal (dashed arrows) and distal (arrows) portions of the compression site (open arrow), showing the suture. The calf muscles show distinct hyperintensities (thick arrows) compared with the surrounding muscles, and the muscle changes are consistent with grade 3.
