Cerebral metabolites in patients with acute and subacute strokes: concentrations determined by quantitative proton MR spectroscopy.

Abstract

Quantitative single-voxel proton spectroscopy is feasible for use in clinical studies of acute stroke. Ratio measurements or comparison with contralateral metabolites may be misleading because all metabolites may change during infarction, and contralateral metabolite levels may also be different from normal subjects.
