Cardiac imaging software developer Circle Cardiovascular Imaging subsidiary Circle Neurovascular Imaging has received clearance for its StrokeSens acute stroke detection software from Health Canada and the Therapeutic Goods Administration (TGA) in Australia.
The artificial intelligence (AI)-based software is designed to provide automated detection and notification of suspected anterior circulation large-vessel occlusions (LVOs) on contrast-enhanced CT angiography exams, according to the vendor.
The algorithm can also analyze noncontrast-enhanced CT exams to provide automated Alberta Stroke Program Early CT Scoring (ASPECTS) assessment of regions with suspected acute ischemic tissue, Circle Neurovascular said.
With the new clearances, StrokeSens is now available for clinical use in the European Union, U.K., Canada, and Australia. It's also available in the U.S. for detection of LVO only, the company said.
![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
