MR neurography is an important non-invasive method to know the 3D structure of brachial plexus. 3D T2 Fast Spin Echo with STIR (Short Tau Inversion Recovery) is often used for homogenous fat saturation. STIR and Two Point Dixon were compared in this study. Nerve signal could be separated from fat and background signals in both methods. Noise is lower in Two Point Dixon method and vessel connectivity was improved.
