Evaluating blood flow in acute ischemic stroke using advanced imaging techniques

Application of a Noninvasive Quantitative Assessment System for Cerebral Perfusion Function in the "Green Channel" of Acute Stroke

Observational Xuanwu Hospital, Beijing · NCT05213793

This study is testing a new imaging technique to see if it can better measure blood flow in the brains of people who have had an acute ischemic stroke.

What this trial studies

This observational study investigates the effectiveness of multi-delay arterial spin labeling (ASL) in assessing cerebral blood flow in patients with acute ischemic stroke. A total of 200 patients will be enrolled and undergo various imaging techniques, including CTP and multi-delay ASL, to evaluate perfusion levels and the extent of reversible ischemic injury. The study aims to compare the accuracy and quality of these imaging methods in diagnosing stroke and predicting clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals who have experienced an ischemic stroke within the last 24 hours and have anterior circulation occlusion confirmed by imaging.

Not a fit: Patients who are pregnant or have contraindications to MRI scans will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of stroke diagnosis and improve patient management strategies.

How similar studies have performed: Previous studies have shown promising results with advanced imaging techniques in stroke diagnosis, suggesting potential for success in this approach.
