MRN technique. 3T MR neurography imaging sequences with isotropic multiplanar reconstruction. 3D T2 SPACE with multiplanar reconstruction of the cervical spine (medium arrows). Axial T1-weighted image shows the bilateral brachial plexus through the lower aspect of the scalene triangle (small arrows). Coronal MIP 3D STIR SPACE image shows the brachial plexus (thick arrow). Sequential sagittal STIR images show the normal and symmetric C5-T1 nerve roots (curved arrows), trunks (circle), and cords (oval).
