Maximum intensity projections, angulated to the left carotid bifurcation (slab thickness: 15 mm), in a 71-year-old man with multiple embolic ischemia of the left precentral gyrus indicating an extracranial internal carotid artery stenosis (wide arrows, grade 2) in REACT (water-only) and CE-MRA. Source images of REACT (axial plane) clearly reveal an adjacent plaque of predominantly hyperintense signal, while its visibility is hampered in CE-MRA (thin arrows). *, internal jugular vein. REACT, relaxation-enhanced angiography without contrast and triggering; CE-MRA, contrast-enhanced magnetic resonance angiography.
