Fig 1.
A patient with carotid artery occlusion.
A: FVH was found in one image of the FLAIR sequence, that was located at the proximal segment; therefore, this patient was defined in the Low FVHs patients and Proximal FVH patients respectively; B: DWI sequence indicated a massive cerebral infarction of the left hemisphere; C: carotid MRA showed distal occlusion of the left internal carotid artery.
Fig 2.
A patient with carotid artery occlusion.
A: FVH was found in more than 4 images in the FLAIR sequence, which were located both at the proximal and distal segments; therefore, this patient was defined as the High FVHs and Distal FVH, respectively; B: DWI sequence indicated perforating artery infarct + cortical branch infarct; C: carotid MRA showed distal occlusion of the right internal carotid artery.
