ACR Radiology AI Governance Standard

Radiology just got its first-ever rulebook for AI. 🧠

For years, hospitals and imaging centers have been adopting AI tools with very little structure around how to evaluate them, monitor them, or hold them accountable. That just changed.

In May 2026, the American College of Radiology and SIIM formally approved the first-ever Practice Parameter for Imaging Artificial Intelligence. This is not a white paper or a recommendation. It is a ratified governance standard.

Here is what the new framework actually covers:

– How to select AI tools before you deploy them
– How to run local acceptance testing before going live
– How to monitor AI performance after deployment
– How to handle governance, security, compliance, and training
– Special guidance for models that are not FDA-regulated

The ACR also launched Assess-AI alongside the parameter, described as the world’s first AI quality registry and data service for imaging. It collects anonymized, real-world performance data and compares it to national benchmarks so sites can see how their AI is actually performing in practice, not just in a controlled trial.

Practices that implement AI responsibly under this framework can earn a new designation: ACR Recognized Center for Healthcare-AI, or ARCH-AI.

This matters for more than radiologists. The framework applies to technologists, medical physicists, IT and informatics teams, data scientists, and administrators. If your organization is using imaging AI in any capacity, this standard now sets the baseline for what responsible deployment looks like.

Here is the harder question this raises.

How many imaging centers currently have zero formal process for monitoring AI after go-live? How many purchased an AI tool, activated it, and assumed it would keep working correctly without any oversight?

The ACR is sending a clear signal: deploying AI is not the finish line. Governing it is.

This kind of infrastructure is exactly what the field has needed. The gap between AI adoption and AI accountability has been one of the most underappreciated risks in healthcare technology.

The first specialty to build a real quality registry for AI is radiology. That says a lot about where the profession is heading.
