Artificial intelligence technology is a rapidly expanding field with many applications in acute stroke imaging, including ischemic and hemorrhage subtypes. Early identification of acute stroke is critical for initiating prompt intervention to reduce morbidity and mortality. Artificial intelligence can help with various aspects of the stroke treatment paradigm, including infarct or hemorrhage detection, segmentation, classification, large vessel occlusion detection, Alberta Stroke Program Early CT Score grading, and prognostication. In particular, emerging artificial intelligence techniques such as convolutional neural networks show promise in performing these imaging-based tasks efficiently and accurately. The purpose of this review is twofold: first, to describe AI methods and available public and commercial platforms in stroke imaging, and second, to summarize the literature of current artificial intelligence-driven applications for acute stroke triage, surveillance, and prediction.
人工智能技术是一个快速发展的领域,在急性中风成像中有许多应用,包括缺血性和出血性亚型。早期识别急性中风对于启动及时干预以降低发病率和死亡率至关重要。人工智能可以帮助中风治疗模式的各个方面,包括梗死或出血检测、分割、分类、大血管闭塞检测、阿尔伯塔中风计划早期 CT 评分分级和预后预测。特别是,卷积神经网络等新兴人工智能技术在高效、准确地执行这些基于成像的任务方面显示出了前景。本综述的目的有两个:首先,描述中风成像中的 AI 方法和现有的公共和商业平台;其次,总结当前人工智能驱动的急性中风分诊、监测和预测应用的文献。
