Comparison of MR findings of acute traumatic peripheral nerve injury and acute compressive neuropathy in a rat model
Fig 5
MR images of the rat with crush injury 10 days after the surgery.
In the oblique coronal (A, B) and axial (C, D) fat-suppressed T2-weighted images, the injured nerve (arrows) is observed as a thick hyperintense structure, suggesting grade 3 nerve change. However, the nerve change is more prominent distal to the injury and subtle proximal (dashed arrows) to the injury. The calf muscles are distinctly hyperintense (thick arrows) compared to the surrounding muscles, suggesting grade 3 muscle change.
