The assessment of brain volume change with serial MRI provides an objective measure of an important component of the pathology of multiple sclerosis. Glatiramer acetate (GA) has a beneficial effect on clinical and MRI measures of disease activity and burden in patients with relapsing-remitting (RR) multiple sclerosis. This study investigated...

BACKGROUND AND PURPOSE: Despite extensive use of MR imaging to provide markers of multiple sclerosis (MS) activity and accumulated disease burden, the magnitude of the relationship between clinical and MR findings is still debated. Using data from the European/ Canadian glatiramer acetate (GA) trial, we investigated short-term correlations...

Glatiramer acetate (GA) is effective in reducing clinical and magnetic resonance imaging (MRI) activity in relapsing -remitting multiple sclerosis (RRMS). Serial long-term MRI data are lacking for large cohorts of GA-treated patients. The European/Canadian GA study consisted of two consecutive phases, each lasting nine months. The first...
