Fig. 6:

Comparisons of diffusion/pH/perfusion deficits, pH/diffusion and perfusion/pH scatterplots in two acute stroke patients at 1 day from symptom onset. a-c: A patient with pH/perfusion mismatch, but minor diffusion/pH mismatch. d– f: A patient with pH/perfusion mismatch, as well as diffusion/pH mismatch. The distributions of the diffusion deficit area (red), pH-diffusion mismatch (green), and perfusion-pH mismatch (blue) were markedly different from those of the contralateral normal tissue (black).
