Circle Neurovascular Imaging
About Circle Neurovascular Imaging
Circle Neurovascular Imaging (Circle NVI) is a healthcare AI company dedicated to revolutionizing stroke diagnosis and treatment. Leveraging AI-assisted advanced technology, their flagship product, StrokeSENS, empowers frontline healthcare clinicians to more rapidly identify strokes and make swift, accurate decisions regarding patient care. This clinically validated technology has received clearances from Health Canada and the FDA, and the company has partnered with GE Healthcare for its implementation across health systems.
StrokeSENS is designed to provide automated detection and notification of suspected anterior circulation large-vessel occlusions (LVOs) on contrast-enhanced CT angiography exams. Furthermore, the algorithm can analyze noncontrast-enhanced CT exams to offer automated Alberta Stroke Program Early CT Scoring (ASPECTS) assessment for regions with suspected acute ischemic tissue. This technology significantly supports quick identification, accurate image interpretation, effective patient transport decisions, and assists healthcare professionals, particularly in remote and rural areas where specialized expertise may be limited. Circle NVI operates as a subsidiary of Circle Cardiovascular Imaging, a recognized leader in cardiac imaging solutions.

What Physicians Need to Know
For physicians, Circle Neurovascular Imaging's StrokeSENS platform stands out by enabling significantly faster and more accurate decision-making in acute stroke cases, where every second counts. The AI-powered LVO detection and automated ASPECTS scoring reduce subjectivity and standardize evaluations, leading to more consistent and reliable diagnoses. Its seamless integration into existing workflows and real-time mobile notifications streamline the stroke care pathway, reducing clerical burden and improving patient throughput. Furthermore, the ability to provide advanced stroke assessment from routine CT/CTA, even when CTP or MRI is unavailable, makes it a valuable tool for front-line clinicians, especially in remote or underserved areas. The clinically validated nature of the technology provides confidence in its diagnostic capabilities.
Circle Neurovascular Imaging's StrokeSENS is designed to be vendor-agnostic and seamlessly integrates into existing radiological environments, including PACS. It supports integration via AI marketplaces or distribution platforms and can be deployed locally on dedicated hardware or virtualized environments (VM, Docker). This flexibility ensures compatibility with various hospital IT infrastructures and workflows, minimizing disruption upon adoption. The output, including perfusion heatmaps and occlusion alerts, is provided in DICOM format for easy incorporation into existing systems.
