Magnetic resonance neurography (MRN) of the brachial plexus using a 3D turbo spin echo (TSE) sequence with short-term inversion recovery (STIR) reduces the effect of fat suppression at 3.0 T. In addition, the signal intensity of the brachial plexus is influenced by changing the effective echo time (TEeff). Therefore, we optimized the fat suppression technique and TEeff so that the 3D TSE sequence, using a combination of STIR with SPIR and an optimal TEeff (from170 ms to 293 ms), achieved better visualization of the brachial plexus without residual fat.
