Ischemic Stroke
Conditions
Brief summary
cELVO is a software that has been pre-learned based on a large vessel occlusion diagnosis model using brain CT images, and clinical decision support system for diagnosing large vessel occlusion by automatically analyzing brain CT images by assisting the medical team. The specific aims of this study are to evaluate efficacy of cELVO compared to the sensitivity and specificity levels of medical team to diagnosis with and without cELVO used.
Interventions
The medical team visually checks the non-contrast CT without cELVO and diagnose the large vessel occlusion.
The medical team visually checks the non-contrast CT with assistance from the cELVO and diagnose the large vessel occlusion.
