We developed a carotid MRS protocol to non-invasively test the relation between the lipid to water ratio at the location of the carotid artery wall and carotid artery wall dimensions. We found that the lipid:water ratio correlated with the carotid artery wall dimensions, independent of serum lipid levels. Further research is needed to resolve whether MRS is a useful tool to assess the efficacy of lipid altering pharmacotherapy in the treatment of advanced atherosclerotic lesions.
