For each sequence and reader, FA values are shown as mean ± SD for each level of the brachial plexus from C5 to TH1 for both sides. Paired sample t-tests were performed to assess potential between group differences. Corresponding P-values are given. rs-DTI, readout-segmented echo planar diffusion-tensor imaging; SD, standard deviation; ss-DTI, single-shot echo planar diffusion-tensor imaging.
