Study Shows AI’s Economic Value

One of the biggest criticisms of AI for radiology is that it hasn’t demonstrated its return on investment. Well, a new study in JACR tackles that argument head on, demonstrating AI’s ability to both improve radiologist efficiency and also drive new revenues for imaging facilities. 

AI adoption into radiology workflow on a broad scale will require significant investment, both in financial cost and IT resources. 

  • So far, there have been few studies showing that imaging facilities will get a payback for these investments, especially as Medicare and private insurance reimbursement for AI under CPT codes is limited to fewer than 20 algorithms. 

The new paper analyzes the use of an ROI calculator developed for Bayer’s Calantic platform, a centralized architecture for radiology AI integration and deployment. 

  • The calculator provides an estimate of AI’s value to an enterprise – such as by generating downstream procedures – by comparing workflow without AI to a scenario in which AI is integrated into operations.

The study included inputs for 14 AI algorithms covering thoracic and neurology applications on the Calantic platform, with researchers finding that over five years … 

  • The use of AI generated $3.6M in revenue versus $1.8M in costs, representing payback of $4.51 for every $1 invested
  • Use of the platform generated 1.5k additional diagnoses, resulting in more follow-up scans, hospitalizations, and downstream procedures
  • AI’s ROI jumped to 791% when radiologist time savings were considered
  • These time savings included a reduction of 15 eight-hour working days of waiting time, 78 days in triage time, 10 days in reading time, and 41 days in reporting time  

Although AI led to additional hospitalizations, it’s possible that length of stay was shorter: for example, reprioritization of stroke cases resulted in 264 fewer hospital days for patients with intracerebral hemorrhage. 

  • Executives with Bayer told The Imaging Wire that while the calculator is not publicly available, the company does use it in consultations with health systems about new AI deployments. 

The Takeaway

This study suggests that examining AI through the lens of direct reimbursement for AI-aided imaging services might not be the right way to assess the technology’s real economic value. Although it won’t settle the debate over AI’s economic benefits, the research is a step in the right direction.

Bayer Establishes AI Platform Leadership with Blackford Acquisition

Six months after becoming radiology’s newest AI platform vendor, Bayer accelerated its path towards AI leadership with its acquisition of Blackford Analysis.

The acquisition might prove to be among the most significant in imaging AI’s short history, combining Blackford’s many AI advantages (tech, expertise, relationships) with Bayer’s massive radiology presence and AI ambitions. 

After closing later this year, Blackford will operate independently through Bayer’s well-established “arm’s length” model, allowing Blackford to preserve its entrepreneurial culture, while leveraging Bayer’s “experience, infrastructure and reach” to drive further expansion.

Bayer’s Calantic platform and team will operate separately from Blackford, providing Bayer customers with two distinct AI platforms to choose from, while giving Bayer two ways to drive its AI business forward. 

Although few would have predicted this acquisition, it makes sense given Bayer and Blackford’s relatively long history together and their complementary situations. 

  • Blackford was part of Bayer’s 2019 G4A digital health accelerator class
  • The companies have been working together to develop Calantic since 2020
  • Bayer has big AI goals, but its AI customer base and reputation were unestablished
  • Blackford’s AI customer base and reputation are solid, but it needed a new way to scale and a positive exit for its shareholders

Even fewer would have predicted that imaging contrast vendors would be the driving force behind AI’s next consolidation wave, noting that Guerbet invested in Intrasense just last week. However, imaging contrast and imaging AI could serve increasingly interrelated (or alternative) roles in the diagnostic process, and there’s surely advantages to being a leader in both areas for Bayer and Guerbet.

Speaking of AI consolidation, it appears that all those 2023 AI consolidation forecasts are proving to be correct, while bringing some of radiology’s largest companies into an AI segment that’s historically been dominated by startups. It wouldn’t be surprising if that trend continued.

The Takeaway

Bayer and Blackford have been working on their AI strategies for years, and this acquisition appears to give both companies a much better chance of achieving long-term AI leadership. Considering that AI is still in its infancy and could eventually play a dominant role in radiology (and across healthcare), AI leadership might be a far more significant market position in the future than many can imagine today.
