An algorithm was developed to determine the volume flows to specific brain areas, i.e., regional cerebral volume flow, and to determine the distribution of cerebral volume flows within different regions of the brain circulation in healthy volunteers. The study population consisted of eighty-three healthy volunteers. All subjects underwent quantitative Magnetic Resonance Angiography (QMRA) study with a standard NOVA head-and-neck protocol (VasSol, Inc., Chicago). Twelve regions in the brain circulation were identified in a partition tree and the volume flow for each region was determined based on the QMRA study results.
