BACKGROUND AND PURPOSE: In acute ischemic stroke, the amount of neuronal damage in hyperintense areas on MR diffusion imaging (DWI) is unclear. We used spectroscopic imaging to measure N-acetyl aspartate (NAA, a marker of normal neurons) and lactate (a marker of ischemia) to compare with diffusion and perfusion values in the diffusion lesion in acute ischemic stroke. METHODS: We recruited patients with acute ischemic stroke prospectively and performed MR diffusion weighted (DWI), perfusion, ...Expand abstract
