A spinoff of the Medical University of Vienna (MUW), contextflow develops deep learning-based software to improve radiology workflows, saving radiologists time and improving reporting quality. Its core technology is a 3D image-based search engine (SEARCH), which detects disease patterns in 3D medical images like CTs and MRIs. It is currently being utilized by radiologists on lung CTs, identifying 19 different patterns (including those related to COVID-19), making it the only clinical decision support system of its kind. Another unique feature of SEARCH is its transparency, meaning radiologists can easily see and understand why the algorithm provided a given result. Plus, it integrates directly into various PACS systems, providing reference cases based on visual disease pattern detection, statistics, and medical literature necessary for differential diagnosis.

Key people 🧑‍🤝‍🧑


  • Expandable tech: Whereas many AI companies focus on very specific diseases and offer only black-box decision support systems, contextflow takes a general approach and develops software that can be extended to additional modalities and organs. This makes contextflow the broadest AI software in the radiology field worldwide.
  • It works: The study, in collaboration with the Medizinische Universität Wien and Universitätsklinikum AKH Wien shows reading time decreased by 31% when contextflow SEARCH Lung CT was available for use. 🔗
  • Instant insights: contextflow delivers quantitative and qualitative insights for ILD, COPD, lung cancer and even COVID-19 directly in the default viewer. 🔗
  • It's integrated: contextflow develops the components necessary for deep integrations, so comprehensive chest CT insights are available to users directly in their native PACS viewer. No clickouts necessary. 🔗
  • Quantitative profiling: contextflow can help doctors and pharmacists to create cohorts of similar patients based on image characteristics or predict risk outcomes or treatment responses. 🔗

Alexander Sommer-Fein, Managing Director at Peak Pride and its HPH Start-up Unit 🔗
At Dubrava University Hospital, we take pride in providing the best care possible to our patients. There are many AI radiology solutions, but we agreed to the proof of concept with contextflow because their solution provides real value, particularly for new residents.
Boris Brkljacic, President of the European Society of Radiology
I really like the transparency of contextflow SEARCH as opposed to other black box AI solutions. It's designed to support my workflow while leaving the final decision up to me.
Elmar Kotter, Vice Chair and Head of Imaging Informatics at the Department of Radiology at Freiburg University Medical Center
contextflow SEARCH Lung CT is one of the applications that certainly fits radiology's current needs and can simplify the analysis of complex lung pathology. With the right insights and technology, we can succeed in introducing AI in a very attractive way to radiology departments on a global scale.
