A 62-year-old woman with left internal carotid artery stenosis. Magnetic resonance angiography shows that the left internal carotid artery disappears (A). The vector map of time-resolved 3D phase-contrast (4D-Flow) MRI shows the antegrade flow of the affected-side the ophthalmic artery (OphA) (B). The rest and acetazolamide stress single photon emission computed tomography (SPECT) images show that cerebral blood flow and cerebral vascular reserve did not decrease in the territory of middle cerebral artery (MCA) (C).
