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

Figure 3 Sixty-eight-year-old male patient with two new ipsilateral ischemic lesions after left carotid artery stenting (Patient No. 19). A-B: Focal acute ischemic lesion in the left middle frontal gyrus cortical surface that is hyperintense in diffusion-weighted imaging (arrow) but hypointense in apparent diffusion coefficient mapping (arrow); C: Ischemic lesion volume (0.263 cm³) measured by the first observer is illustrated; D-E: Focal ischemic lesion during acute phase in the left superior frontal gyrus lateral cortical surface that is hyperintense in diffusion-weighted imaging (arrow) but hypointense in apparent diffusion coefficient mapping (arrow); F: Ischemic lesion volume (0.577 cm³) measured by the second observer is illustrated.
