Nines
About Nines
Nines was a healthcare AI company dedicated to transforming radiology through the integration of advanced artificial intelligence and data science with teleradiology services. Its primary objective was to enhance patient outcomes and improve radiologist efficiency by developing AI-powered tools for prioritizing critical medical cases. The company’s initial offerings included the Emergent Neuro Suite, a software designed to aid in the rapid review of head CT images for emergent conditions such as intracranial hemorrhage and mass effect, aiming to facilitate quicker diagnoses for patients requiring urgent attention. Nines also developed NinesMeasure, an AI-powered algorithm for lung nodule analysis.
In February 2022, Sirona Medical acquired Nines’ artificial intelligence capabilities and technology. This acquisition encompassed Nines’ clinical data pipeline, machine learning engines, AI-powered radiology workflow management and analytics tools, and its two FDA-cleared medical devices: NinesMeasure and NinesAI Emergent Triage. These AI algorithms are now integrated into Sirona Medical’s radiology operating system (RadOS), a unified platform that combines various radiology applications. While Nines’ teleradiology business, Nines Radiology, was not part of this acquisition, the AI innovations developed by Nines are now part of Sirona Medical’s offerings, continuing their mission to support radiologists with more efficient workflows and improved patient care.

What Physicians Need to Know
For physicians, Nines' technology stands out by directly addressing key challenges in radiology. Their FDA-cleared AI tools for intracranial hemorrhage, mass effect, and lung nodule measurement are designed to significantly improve diagnostic efficiency and accuracy, particularly for time-sensitive conditions. The integration of AI into the workflow aims to reduce radiologist burnout by automating non-diagnostic tasks and intelligently prioritizing emergent cases, allowing radiologists to focus on critical interpretations and patient care. The unique collaboration between radiologists and engineers in developing these tools ensures clinical relevance and usability, ultimately leading to faster diagnoses and potentially better patient outcomes.
