Results of glucoCEST-MRI and fMRS experiments upon hyperoxia. Group mean time courses of −1.2 ppm and +1.2 ppm CEST signals (a,b) and Iratio (1.2 ppm) changes upon hyperoxia (c) (n = 3 animals, 3 independent data sets). (d) Group mean time courses of the water peak chemical shift obtained by analyzing fMRS data acquired from a 8-mm3 voxel (n = 2 animals, 5 independent data sets).
