Keywords: Nerves, NervesWe assessed proximal-distal longitudinal signal and size alterations of brachial plexus nerve roots in amyotrophic lateral sclerosis (ALS) patients using 3D nerve-sheath signal increased with inked rest-tissue rapid acquisition of relaxation enhancement imaging (3D SHINKEI) . The conclusion confirmed proximal-distal longitudinal diameters and SNR values decreased significantly for brachial plexus nerve roots in ALS patients with larger differences in slopes compared to the HC. Thus, the size and signal alterations of brachial plexus nerve roots using 3D SHINKEI can be used to supplement clinical diagnosis for ALS patients.
