The study sought to better characterise disease related brain tissue changes in amyotrophic lateral sclerosis (ALS) using tract based spatial statistics (TBSS) and regional analyses both on DTI and R2* data. The latter served to quantify iron deposition in deep gray and white matter, focussing on changes along the corticospinal tract. R2* measurements appeared to be more sensitive over DTI in detecting tissue abnormalities.
