An expert panel naming AI-based tools its most-debated topic, then advising caution, is worth sitting with.
- The Brain Attack Coalition — neuroradiologists, neurologists, interventionalists, and the NIH — published a 2026 stroke-imaging consensus in AJNR.
- It calls non-contrast CT (NCCT) and CT angiography (CTA) "essential" at Primary Stroke Centers (PSC). Perfusion and MRI are "strongly recommended," not required.
- AI-based tools were the most-deliberated topic. The verdict: promising, "supportive," and to be "implemented with caution."
- The frame throughout was access: what is feasible at centers with very different resources.
Start with what is actually mandatory at the average Primary Stroke Center: NCCT and CTA. Not perfusion. A tool that assumes advanced imaging quietly writes off the hospitals with the least. The rest of the message is about adoption. "Implement with caution" is really a specification: validate it, monitor it, make it fit the read. Centers that take the consensus seriously will press harder on whether an algorithm holds up across scanners, sites, and the 3 a.m. study. That is the bar this technology should clear.
This is what a maturing field sounds like. The question has moved from "can it detect the clot?" to "does it hold up everywhere we work, and does it fit the workflow we run?" The access framing changes what modernization means, too. The win is not the flagship academic center adding one more algorithm. It is the resource-limited hospital getting dependable triage on the scans it already has.
If a stroke tool only works where perfusion and around-the-clock neuroradiology already exist, is it closing the access gap or widening it? Keen to hear how others validate for the centers that have the least.
