Fig 1 Diffusion-weighted images (top row) and average diffusion coefficient maps (bottom row) obtained in a 71-year-old patient imaged 48 hours after carotid stenting show multiple punctate areas of restricted diffusion in the right middle cerebral artery vascular territory, mostly in a cortical/subcortical distribution (arrows). A single lesion is seen in the periventricular white matter of the centrum semiovale.

Fig 2 Diffusion-weighted images obtained in a 62-year-old patient imaged 48 hours after carotid stenting show lesions, including a single acute lesion in the left medial occipital lobe (arrow), in the territory of the left posterior cerebral artery.

Fig 3 Diffusion-weighted images in a 78-year-old patient imaged 48 hours after carotid stenting show multiple punctate foci of restricted diffusion (arrows) in the left middle cerebral artery territory with lesions on the contralateral side. Again, distribution of lesions predominates at the cortico/subcortical junction, with a few lesions in the deep white matter.
