2、tract】Objective To investigate the feasibility of plain and enhanced 3D-STIR sequence on 3.0T MR scanner in detection of spinal nerves and its clinic value. Methods 26 volunteers for brachial plexus and 20 volunteers for

3、 lumbosacral plexus received conventional scanning sequence, 3D-STIR sequence and enhanced 3D-STIR sequence on 3.0T MR scanner. The images acquired was evaluated and compared with the standard anatomica pictures. Results

4、: Plain and enhanced 3D-STIR sequence could clearly display brachial plexus and lumbosacral plexus, course, continuity, shape and signal of volunteer, and the enhanced 3D-STIR sequence improved the suppression effects of
