Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by loss of upper and lower motor neurons (UMN and LMN), resulting in muscle atrophy and eventual death. Clinical indicators such as ALSFRS-R scores can be confounded by inter-rater variability and low sensitivity. MR Cytography based TRATE has been shown to identify changes to myofiber microstructure. This work aims to demonstrate that TRATE is a more sensitive and consistent metric to evaluate longitudinal muscle degeneration in ALS patients than existing clinical indicators such as ALSFRS-R scores.
