Evaluation of ischemic lesions after carotid artery stenting with diffusion-weighted imaging

Figure 4 Eighty-four-year-old male patient with new contralateral ischemic lesion after left carotid artery stenting (Patient No. 26). A-B: Focal acute ischemic lesion in the right middle frontal gyrus cortical-subcortical surface that is hyperintense in diffusion-weighted imaging (arrow) but hypointense in apparent diffusion coefficient mapping (arrow); C: Ischemic lesion volume (5.506 cm³) measured by the first observer is illustrated.
