The Added Value of Vessel Wall MRI Over CTA for Differentiating Large-Artery Atherosclerotic and Cardioembolic Stroke in the Anterior and Posterior Circulations.
BACKGROUND AND PURPOSE Differentiation between stroke etiologies is essential for secondary prevention; however, etiologic classification remains challenging in many ischemic strokes. We evaluated whether magnetic resonance vessel wall imaging (VWI) plaque markers improve computed tomography angiography (CTA)-based dif...
