PURPOSE To assess the relationship between sodium signal intensity changes and oligemia, measured with perfusion-weighted imaging (PWI), in ischemic stroke patients. MATERIALS AND METHODS Nine ischemic stroke patients (55 ± 13 years), four with follow-up scans, underwent sodium and proton imaging 4-32 hours after symptom onset. Relative sodium intensity was calculated as the ratio of signal intensities in core (identified as hypertintense lesions on diffusion-weighted imaging [DWI]) or… CONTINUE READING
