Fig. 9.

(a) Proton apparent diffusion coefficient (ADC) map image post right middle cerebral artery occlusion. Ischemic core (absent perfusion) is indicated by ADC values <5.30 × 010⁻⁴ mm²/s (circled by blue line). (b) Corresponding hp ¹²⁹Xe chemical shift image displayed in arbitrary units with the greatest signal originating from healthy brain tissue and an obvious signal void corresponding to the ischemic core. (c) 2,3,5-triphenyltetrazolium chloride (TTC)-stained brain section of the same animal. (d) Tricolor map based on the ADC and TTC images shown in (a) and (c) with healthy brain tissue (green), ischemic core (red) and penumbra (blue). Reprinted with permission from Zhou et al.
