Radiology startup Sirona Medical acquires Nines’ AI, some employees

Start up radiology Sirona Medical acquires the AI ​​capabilities and some staff from fellow radiology-focused company Nines.

The deal includes Nines’ clinical data pipeline, machine learning engines, AI-enabled workflow management and analytics tools, but not the company’s teleradiology business. Some of the staff will also move to Sirona, including Chief Revenue Officer Maureen Bradford.

Nines is bringing two FDA-approved tools to the startup:

  • NinesMeasure, which was given the green light by the agency About a year ago, AI used to analyze chest CT scans to determine the size of lung nodules.
  • NinesAI, which was cleared in 2020 and analyzes CT images of the head for possible intracranial hemorrhage and/or mass effect so they can be prioritized for immediate care.


Sirona plans to integrate both FDA-cleared devices into its RadOS platform, which aims to integrate software into one system to improve radiologists’ workflow.

“To make AI adoption at scale, you need to break the artificial silos of a medical image viewer, a research worklist, and a speech recognition reporter. Only through a unified platform can AI take full advantage of the underlying data and deliver context-specific results on the most relevant way to radiologists,” Cameron Andrews, founder and CEO of Sirona Medical, said in a statement.

“I’ve been a long-time fan of what Nines has built and we’re excited to add their brilliant minds to the team as we continue to expand our vision of helping radiologists through better software.”


Sirona came out of stealth last August with $22.5 million in Series A funding. Months later, it scored $40 million in a Series B funding round.

Shortly after the Series B, the startup announced it was… partnered with RevealDx to integrate its RevealAI lung algorithm, which has earned CE Mark and Health Canada approval, into Sirona’s platform.

Radiologists are steadily adopting AI in their practice. According to a study published in the Journal of the American College of Radiology last year, about 30% of those surveyed said they currently use AI, and 20% plan to acquire those tools in the next five years.

Other companies in the imaging AI space include Nanox, which recently launched completed the acquisition of Zebra Medical Vision, now Nanox.AI, Aidoc and
