The objective of this work is to optimize the 3D nerve-SHeath signal increased with INKed rest-tissue RARE Imaging (SHINKEI) sequence for the best nerve-muscle T2 contrast in 1.5T and evaluate the clinical feasibility of this optimized sequence in 24 patients with brachial plexus injuries. Based on the evaluation by two experienced radiologists and the comparison to surgical observations, the optimized SHINKEI sequence performed better than fat suppressed TSE (STIR TSE) and Diffusion Weighted Imaging with Background Suppression (DWIBS) sequences that are currently widely used in the clinical protocols
