Images of individuals obtained using perfusion-based imaging techniques or diffusion-based imaging techniques can be analyzed to determine regions of the brains of the individuals where the supply of blood has been disrupted. The images can be used to generate alerts indicating the disruption of blood flow to one or more regions of the brains of the individuals. The images can be used to identify vessel segments (eg M1, M2, M3, M4, . . . ) and branches (MCA, ACA, PCA) of the brains of individuals in which abnormalities may be present.
