AI technology for improving treatment of acute ischemic stroke

Segmentation and Modeling for Accurate Reconstruction of CT Angiography of Intracranial Large Vessel Occlusion with Artificial Intelligence: a Stepped-wedge, Cluster-randomized Controlled Trial

NA · Shanghai Jiao Tong University Affiliated Sixth People's Hospital · NCT06645405

This study is testing a new AI tool to see if it can help doctors get better images of blocked blood vessels in patients with acute ischemic stroke, making it easier and faster to treat them.

What this trial studies

This study evaluates an artificial intelligence (AI) algorithm designed to enhance the reconstruction of CT angiography (CTA) images for patients suffering from acute ischemic stroke caused by large vessel occlusion. The goal is to improve the accuracy of endovascular thrombectomy procedures by reducing the time taken for the first pass through the occluded segment. The study employs a prospective, stepped-wedge cluster-randomized design to assess the clinical utility of the AI algorithm in real-world settings. By integrating this technology into the care flow for acute ischemic stroke, the researchers aim to address challenges faced during treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who present with symptoms of acute ischemic stroke and are found to have an intracranial large vessel occlusion eligible for endovascular treatment.

Not a fit: Patients with severe motion artifacts in their CT imaging may not benefit from this study due to the inaccuracy of the AI algorithm in such cases.

Why it matters

Potential benefit: If successful, this approach could significantly improve the outcomes for patients with acute ischemic stroke by facilitating quicker and more effective treatment.

How similar studies have performed: While the use of AI in medical imaging is a growing field, this specific application for acute ischemic stroke treatment is relatively novel and has not been extensively tested in prior studies.
