Abstract

COMMENTARY Emerging Artificial Intelligence Imaging Applications for Stroke Interventions 10,11 troke is the most frequent cause of acquired disability and the early enough to qualify for MT within 6 hours, but approxi- Sfifth most frequent cause of death in the United States. mately 9% of patients presenting in the 6- to 24-hour time window Treatment options for acute ischemic stroke (AIS) caused by large- may qualify for MT. Second, after the patient arrives at a medical vessel occlusion (LVO) are rapid recanalization of the occluded center, urgent imaging, either CT or MR imaging, is performed and large vessels using IV thrombolysis with alteplase (recombinant tis- must be promptly analyzed by qualified radiologists to determine if sue plasminogen activator) within 4.5 hours and mechanical throm- MT is required. However, image interpretation is subject to incon- bectomy (MT) within 6 hours. In either treatment, identifying a sistent local expertise and time delays and varies between institu- substantial and salvageable ischemic penumbra is essential for a tions.
