## Abstract Acute cerebral ischemia has been shown to be associated with an enhanced transverse relaxation rate in rat brain parenchyma, chiefly due to the blood oxygenation level‐dependent (BOLD) effect. In this study, Carr‐Purcell __R__~2~ (CP __R__~2~), acquired both with short and long time int
