TORONTO, August 27, 2020 ( - Addressing the need for greater insights into patient disease processes such as stroke, cardiovascular disease, or most recently COVID-19, Bialogics Analytics Inc. (Bialogics) today announces the launch of a new deep learning-based natural language processing (NLP) engine that seamlessly integrates into radiology and cardiology PACS workflows, giving providers the tools they require for advanced mining and analysis of structured and unstructured data elements contained within radiology and cardiovascular imaging and information systems to accelerate workflow optimization and clinical research for real-time identification of patient cohorts.

Traditionally, imaging metadata can be extracted from the RIS or PACS using HL7 or DICOM protocols. However, up to 80% of valuable patient information is trapped within the unstructured text of medical reports, making it is impossible for care providers to accurately search, sort, summarize, or visualize this health information. The Bialogics DxPro engine addresses this problem with NLP, unlocking this value by converging insights from traditional imaging metadata with the clinical knowledge contained within unstructured radiology requisitions, reports, and other clinical notes, enabling care providers, administrators, researchers, insurers, and artificial intelligence (AI) developers to get the real-time data they need to enable evidence-driven clinical and technical research and application development initiatives.

Jeff Vachon, President of Bialogics adds: “Existing workflow and analytical tools offered as part of your RIS/PACS are interesting for operational monitoring, but not informative enough for research or transforming patient care. The convergence of imaging metadata with knowledge extracted from patient reports provides a new level of intelligence that has the potential to drive evidence-driven improvements in imaging workflow efficiency and care quality while supporting clinical research initiatives that will continue to advance disease tracking and management in the future.”
