Note:—L indicates left; R, right; SWI ↓, hypointensity; MRA ↓, decreased arterial caliber in the MCA territory; MRA ↑, increased arterial caliber in the MCA territory.
↵a Additional decrease in caliber of the posterior cerebral artery.
↵b Additional decrease in caliber of the posterior and anterior cerebral arteries.
