Contributions to individual vascular territories were quantified using a voxelwise supply fraction algorithm and the results were correlated with MR angiography.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            Vascular territories were consistent with cerebrovascular anatomy and the presence of pathology.
