Agentic orchestration bridges radiology AI's modality fragmentation problem

The development
Researchers propose an agentic framework that orchestrates specialized radiology AI tools to generate comprehensive reports across multiple imaging modalities. Rather than choosing between narrow high-accuracy models and broad but hallucination-prone generalists, the system delegates tasks to modular FDA-cleared components, standardizing how findings flow into structured outputs. Testing on a large multi-modality corpus reveals what production-grade tool composition can achieve, addressing a persistent gap in radiology AI deployment where existing systems remain locked to single modalities or anatomical regions.

The paper doesn't claim the modular approach is more accurate than end-to-end systems. It claims it's more deployable because each component already has regulatory clearance. That's a constraint-driven design choice, not a capability breakthrough.
This directly inverts the finding from the robotics agentic control paper (November 6). That work showed generalist models outperforming specialist architectures on manipulation tasks at 85.6% vs. 49.2%. Here, radiology is deliberately choosing modularity over generalist capability, but for a different reason: regulatory lock-in and liability boundaries, not raw performance. The tension mirrors what MIT flagged in enterprise analytics (November 2) about agentic insight quality being unreliable. In radiology, the bet is that delegating to pre-cleared narrow tools reduces hallucination risk compared to a single generalist model, even if that generalist might score higher on benchmarks. It's a trust problem masquerading as an architecture problem.
If this system achieves FDA clearance as a composite device within 18 months, it validates the modular-for-compliance thesis and likely triggers similar orchestration approaches in other regulated imaging domains (pathology, cardiology). If instead the FDA requires end-to-end validation of the entire agent workflow, the modularity advantage collapses and the field reverts to generalist models.

Generalist models outperform specialist policies in robot manipulation
Generalist AI models are outperforming specialist robot control architectures in manipulation tasks, challenging the dominant paradigm of vision-language-action models. AMP1, a unified framework that adapts commands in real time across single-arm, bimanual, and mobile systems, achieves 85.6% zero-shot success on RoboLab-120 versus 49.2% for leading VLAs. This shift signals that end-to-end agentic control may scale…
