Chemical exchange saturation transfer (CEST) data in
acute stroke patients (within 6 hours of onset) were
acquired to compare nuclear Overhauser enhancement
mediated CEST (NOE-CEST) with apparent diffusion
coefficient (ADC) and pH-weighted imaging using amide
proton transfer (APT). This work is the first
demonstration of NOE-CEST in acute human stroke.
NOE-CEST provides a unique contrast compared to ADC and
pH-weighted imaging in tissue that progresses to
infarction, suggesting that NOE-CEST may offer a new
insight in acute stroke management.
