Two of Germany's leading AI radiology companies are partnering to bring evidence-based mammography AI to providers across Europe.
Vara and deepc are partnering to make evidence-based mammography AI accessible to providers across Europe—and what that means in practice.
Vara, headquartered in Berlin, and deepc, based in Munich, are two of Germany’s most recognised names in AI radiology. Today, we are announcing a partnership that makes Vara available to more screening programmes and diagnostic centres across Europe through the deepcOS® platform.
What Vara is built for
Vara is designed for mammography, screening and diagnostic. We currently support approximately 50% of Germany’s national screening programme, processing around 200,000 cases per month across seven years of continuous deployment.
The clinical evidence comes from the PRAIM study, published in Nature Medicine in January 2025: 12 centres, 460,000 women, routine clinical conditions. +17.6% cancer detection, -43% reading time, -56.7% radiologist workload reduction, all three improving at the same time. Optimising for one at the expense of another is the more common finding in the literature. Since publication, continued development has exceeded even those benchmarks.
What sets Vara apart in that evidence base is how it performs with prior imaging. An independent evaluation across 10,348 screening participants in Sweden compared commercially available AI vendors on positive predictive value. Without priors, Vara scored 9.3%. With one prior, 11.4%. With three priors, 18.0%—above the radiologist benchmark of 10.1%, and a result no other vendor in the evaluation matched or supported. The ability to use multiple priors is a technical capability most competitors do not offer.
What deepc adds
deepcOS® is vendor-neutral AI deployment infrastructure operating across 30+ countries. It handles the integration complexity that makes scaling AI across heterogeneous clinical and IT environments difficult: different PACS systems, different workflows, different regulatory contexts.
For programmes and providers that want to adopt Vara, deepcOS® provides an additional path into existing clinical environments with no change to how radiologists work.
Why this matters
For most programmes, the remaining question is practical: how do we access this, and how do we integrate it without a multi-year IT project. The deepcOS® partnership extends Vara’s reach to providers across Europe who want evidence-based AI for mammography without the integration overhead.
Europe’s screening programmes face growing case volumes, radiologist capacity under pressure, and the need to improve detection without increasing recall rates. The evidence that AI addresses all three exists. Friction in access and integration has slowed adoption. The deepcOS® partnership addresses that directly, extending Vara’s reach to providers across Europe who want evidence-based mammography AI through infrastructure they may already use.
