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

Figure 2 Seventy-six-year-old male patient with new ipsilateral ischemic lesion after left carotid artery stenting (Patient No. 29). A-B: Focal acute ischemic lesion in the occipital lobe cortical-subcortical surface that is hyperintense in diffusion-weighted imaging (arrow) but hypointense in apparent diffusion coefficient mapping (arrow); C: Ischemic lesion volume (2.730 cm³) measured by the first observer is illustrated.
