To characterize new markers of inflammation and neurodegenerative processes in multiple sclerosis (MS), MRSI and DTI were used to study 30 MS patients and 10 control subjects. MRSI showed significant changes in metabolic ratios in between MS clinical forms and DTI fiber tracking showed significant decreases in FA and increases in ADC in semioval white matter region. Metabolic ratios are significantly correlated with diffusivity parameters as well as with the patient disability status.
