Improving Stroke Care in North-Norway Through Artificial Intelligence

Sponsor

University Hospital of North Norway

Enrollment

1,000 participants

Start Date

Jun 1, 2023

Study Type

INTERVENTIONAL

Conditions

Ischemic Stroke

Summary

Prospective observational multi-center intervention study. The study aims to evaluate whether an artificial intelligence (AI) support tool for radiological image processing (StrokeSens, Circle NVI) can accelerate decision making and increase detection rate in patients with an acute ischemic stroke caused by intracranial large vessel occlusion (LVO) or medium vessel occlusion (MeVO) in Northern Norway. Relevant outcomes will be compared between centres with and without available software during the study period.

Eligibility

Min Age: 18 Years

Inclusion Criteria1

Patients with acute stroke symptoms admitted to a participating hospital within 24 hours of symptom onset

Exclusion Criteria1

Patients not available for follow-up assessments (e.g. non-resident)

Interventions

DEVICEAI software StrokeSens (Circle NVI)

Computed tomography (CT) and computed tomography angiography (CTA) imaging studies acquired upon admission will be assessed by the AI software StrokeSENS (Circle NVI). StrokeSENS is CE marked and available for clinical diagnostic purposes in the EU and UK.The software will be a decision support tool in addition to standard radiological services available in all primary stroke centers in Northern Norway where image interpretation is done by a radiologist or resident in radiology. The software can automatically evaluate the presence of ischemic changes in the vascular territory of the middle cerebral artery according to the Alberta Stroke Program Early CT Score (ASPECTS) and occlusions in the intracranial segment of the internal carotid artery and the proximal segments of the middle cerebral artery (MCA). Output to radiologists will be automated ASPECT scoring, automated search for LVO or MeVO.
