A high-resolution MR neurography using 3D fat suppression T2-weighted Cube combined with double inversion recovery (3D FS DIR Cube) was evaluated the feasibility of brachial plexus assessment. 15 normal volunteers were scanned 3D FS DIR Cube, 3D FS T2-weighted Cube (3D FS T2 Cube), and 2D IDEAL water on a 3T MRI scanner using a GEM NV coil. The 3D FS DIR Cube can provide excellent contrast between brachial plexus branch and surrounding tissues and increase the conspicuity of the nerves delineation with uniformed fat suppression and vessels signal suppression compared with 3D FS T2 Cube and 2D IDEAL water.
