Figure 2.

(A–D) Selected example post-operative diffusion (b1000) MRI scans of four separate subjects. (A,B) are representative of subjects in the control cohort. Note the resection cavities seen in the left parietal lobe on both scans which exhibit a minimal rim of hyperintensity surrounding the resection cavity. (C,D) are representative of subjects in the infarct cohort. Note the resection cavity seen in the right temporal lobe on both scans. Also note the larger area of diffusion hyperintensity surrounding the resection cavity representing arterial infarcts.
