Imaging the brachial plexus is a challenge due to its complicated structure. The purpose of this study is to improve the diagnosis ability for brachial plexus 3D-STIR-SPACE technique with contrast agent administration. After contrast agent administration, signals of adjacent vessels were suppressed due to reduction in its T1 relaxation time which became similar to that of fat. The outlines of nerves would be clearer with respect to surrounding tissues.The image of 3D-STIR-SPACE technique with contrast agent was superior to that without contrast agent. It might be a better way to evaluate anatomies and pathologies of the brachial plexus.
