Core and penumbra estimation using deep learning-based AIF in association with clinical measures in computed tomography perfusion (CTP)
In this study, the utilization of a convolutional neural network (CNN)-based arterial input function (AIF) and whether it improves the volumetric estimation of core penumbra was investigated. The authors included 160 acute ischemic stroke patients for this study, who underwent CTP imaging, National Institutes of Health Stroke Scale (NIHSS), and Alberta Stroke Programme Early CT Score (APSECTS) grading. They were
