Anatomical structures have been well defined using magnetic resonance imaging (MRI), and knowledge of arterial territories is now required for the accurate localization of ischemic lesions. Magnetic resonance imaging studies have reevaluated the clinical spectrum of both anterior and posterior circulation strokes. Because topographical, etiological, and clinical spectrums vary, large prospective studies including welldocumented patients are of utmost importance. Classical syndromes have been revisited and new clinical patterns highlighted. However, most recent studies are based on various anatomical supports and sometimes lack anatomical references, in which case, MRI may be considered as an effective means of identifying etiologies according to the location of the infarction. On the other hand, few reports exist in which the arterial vascular territories are well-identified by anatomical studies. This lack of standardization in terms of both arterial territory localization and the planes used to identify them largely undermines the accuracy of such reports. This recent neuroimaging development calls for an accurate, standardized tool for anatomoradioclinical correlations. However, solid knowledge of the general organization of cerebral arterial circulation is the first step to a good understanding of some of the particularities of the arterial territories of the brain. In the present chapter, in order to discuss the arterial supply of blood to the brain in more detail, we have chosen the medium of brain mapping. Arterial territories of the brain are depicted in a form that is directly applicable to neuroimaging slices in clinical practice. We present a morphological .
