Mapping the Supratentorial Cerebral Arterial Territories Using 1160 Large Artery Infarcts

Mapping the Supratentorial Cerebral Arterial Territories Using 1160 Large Artery Infarcts Key PointsQuestionAre there ways to overcome major weakness of the current vascular territorial maps (high variability, particularly of border zones, and maps that were derived from small sample size data)? FindingsIn this cross-sectional study, statistically rigorous maps were generated to delineate territorial border zones using diffusion-weighted magnetic resonance imaging of 1160 consecutive patients with acute supratentorial infarction owing to atherosclerotic intracranial large artery steno-occlusion. Border zones could be defined using either relative infarct frequencies or the Certainty Index that reflects the likelihood of a voxel being a member of a specific vascular territory.

Abstract

Key PointsQuestionAre there ways to overcome major weakness of the current vascular territorial maps (high variability, particularly of border zones, and maps that were derived from small sample size data)? FindingsIn this cross-sectional study, statistically rigorous maps were generated to delineate territorial border zones using diffusion-weighted magnetic resonance imaging of 1160 consecutive patients with acute supratentorial infarction owing to atherosclerotic intracranial large artery steno-occlusion. Border zones could be defined using either relative infarct frequencies or the Certainty Index that reflects the likelihood of a voxel being a member of a specific vascular territory. MeaningThis new topographic brain atlas can be used to objectively define the supratentorial arterial territories and their borders.
