Abstract
A system and method for imaging is presented that includes exciting water-exchangeable spins in oxygen-bearable molecules in a ROI having a change in oxygen status. A proton transfer within the ROI from exchangeable protons within water is detected such that changes in oxygen levels across the ROI are distinguishable.
