Sponsored by Nunaps Inc · Observational
This study evaluates the efficacy of investigational device named Stroke Onset Time Artificial Intelligence(AI) (Model name:NNS-SOT). Using the investigational device, analyze the image and the onset time of occurrence of acute ischemic stroke lesion on the brain image (4.5 hours or more from the onset of symptoms) and evaluate the efficacy of correctly estimating the onset time.
This clinical trial software medical device (Model name: NNS-SOT) is developed based on artificial intelligence algorithms.
Through clinical validation, it will be easier to determine whether the golden hour (4.5 hours) has elapsed at the time of cerebral infarction in the medical field. It can be used for estimation of the onset time of occurrence in acute ischemic stroke.
2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.
This study's enrollment of 474 is above the median of 300 across 771 observational studies indexed under Ischemic Stroke.
