We investigated the effects of a preclinical antioxidant treatment with vitamin E on T2 relaxation time in order to evaluate if T2 is a sensitive non-invasive biomarker for the assessment of therapeutic approaches in the G93A-SOD1 mouse model of amyotrophic lateral sclerosis (ALS). A clear benefit of Vitamin E treatment for a significantly reduced ALS progression was shown in the study by means of MRI and validated by histology. In more general terms, it was shown that the measurement of the relaxation time T2 enables for a longitudinal non-invasive evaluation of therapeutic approaches in the G93A-SOD1 mouse model of ALS.
