Multiple acute nerve root avulsions. A 51-year-old man with loss of function in the left upper extremity due to recent motor vehicle crash. Coronal MIP 3D STIR SPACE (A) and sagittal STIR (B) images show avulsed C6, C7, and C8 nerve roots (arrows) with abnormal morphology due to hemorrhage and edema from a recent injury, obscuring clear details of the nerve roots. Notice the normal C5 nerve root (large arrows in A) and the normal T1 nerve root (small arrow in B).
