Fig. 2From: Aortic atheroma as a source of stroke – assessment of embolization risk using 3D CMR in stroke patients and controlsExamples of embolization pathway mapping using 4D flow CMR. a A plaque located in the ascending aorta (white region of interest (ROI)) has potential embolization pathways to all brain territories. b A plaque in the aortic arch (white ROI) has potential antegrade embolization pathways via the LSA and retrograde pathways via the LCCA. c A plaque in the distal arch (i.e. proximal descending aorta; white ROI) shows potential retrograde embolization pathways via the BcT, LCCA and LSABack to article page
