Nós apresentamos um procedimento experimental para medir a pressão parcial de oxigênio (pO2) na vasculatura cerebral com base em oxigênio-dependente de têmpera de fosforescência. Preparação de animais e procedimentos de imagem foram delineadas para ambos grande campo de visão de imagem CCD-base de pO2 em ratos e dois fótons de imagens de excitação baseada em pO2 em camundongos.
