tHI caused prolonged deficits in cortical oxygenation. Doppler flow imaging and 3D reconstruction showed reduced perfusion in the ipsilateral hemisphere and the reversal of blood flow in the RICA in the Circle of Willis after RCCAO. Co-registered anatomical image (B-mode micro-US) and StO2 (StO2 in a red-white-blue color-map by PAI) showed bilateral difference in StO2 between the left (L, contralateral) and right (R, ipsilateral) cerebral cortex of an adult C57BL/6 mouse after RCCAO in normoxic (20.9% O2) or hypoxic (7.5% O2) conditions [16]
