Artificial intelligence (AI) software developer RapidAI has secured $25 million (21 million euros) in funding, which it plans to use to support further development of its AI software for cerebrovascular imaging around the world.
Rapid AI's Rapid platform uses AI algorithms to process images from noncontrast CT, CT angiography, CT perfusion, and MRI diffusion and perfusion scans. The platform includes Rapid ICH, Rapid Aspects, Rapid CTA, Rapid LVO, Rapid CTP, and Rapid MRI, and has been trained on more than 1 million scans taken from 1,600 hospitals around the world, the company said.
The funding comes from Lennertz & Co. of Hamburg, Germany, according to the firm.
![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)
