An Algorithm for the Labeling and Interactive Visualization of the Cerebrovascular System of Ischemic Strokes [PDF]
arXiv, 2022 During the diagnosis of ischemic strokes, the Circle of Willis and its surrounding vessels are the arteries of interest. Their visualization in case of an acute stroke is often enabled by Computed Tomography Angiography (CTA). Still, the identification and analysis of the cerebral arteries remain time consuming in such scans due to a large number of ...

Predicting Thrombectomy Recanalization from CT Imaging Using Deep Learning Models [PDF]
Medical Imaging with Deep Learning 2022, 2023 For acute ischemic stroke (AIS) patients with large vessel occlusions, clinicians must decide if the benefit of mechanical thrombectomy (MTB) outweighs the risks and potential complications following an invasive procedure. Pre-treatment computed tomography (CT) and angiography (CTA) are widely used to characterize occlusions in the brain vasculature ...
