Maximum intensity projections, angulated to the left carotid bifurcation (slab thickness: 20mm), in a 65-year-old woman with ischemia of the left frontal lobe depicting a multisegmental stenosis of the extracranial internal carotid artery (wide arrows) with improved delineation of the stenosis in REACT (water-only reconstructions) compared to a blurred appearance in CE-MRA due to a higher noise. REACT, relaxation-enhanced angiography without contrast and triggering; CE-MRA, contrast-enhanced magnetic resonance angiography.
