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.
