Automated Assessment of Hypoperfusion Intensity Ratio in Stroke

This white paper discusses the role of the Hypoperfusion Intensity Ratio (HIR) in the management of acute ischemic stroke, particularly in patients with large vessel occlusion. It outlines how HIR serves as a quantitative measure of collateral circulation, with lower values indicating better collateral flow and correlating with improved clinical outcomes. The paper details the automated calculation of HIR by RapidAI's imaging solutions, which enhances the evaluation process for clinicians. It also presents research findings that demonstrate HIR's correlation with collateral status, prediction of infarct growth, and association with underlying pathologies. Furthermore, the paper addresses challenges in HIR standardization and how RapidAI's technology mitigates variability in measurement techniques. The integration of HIR assessment into clinical practice is shown to support timely decision-making, thereby improving patient outcomes. The conclusion emphasizes the significance of RapidAI's automated HIR assessment in enhancing stroke diagnosis and treatment.
