Hemodynamic Failure Staging With Blood Oxygenation Level–Dependent Cerebrovascular Reactivity and Acetazolamide‐Challenged ( ¹⁵ O‐)H ₂ O‐Positron Emission Tomography Across Individual Cerebrovascular Territories

Abstract

Standardized and clinically accessible BOLD-CVR examinations harbor sufficient data to provide specific cerebrovascular reactivity cutoff points for HF staging across individual vascular territories in symptomatic patients with unilateral cerebrovascular steno-occlusive disease.
