Aidoc vs RapidAI
RapidAI sells CT perfusion alongside CTA, ASPECTS, LVO and ICH modules, and a 2024 AJNR study found that its perfusion volumes and Viz.ai's are not interchangeable. Aidoc's listed neurovascular modules cover stroke, hemorrhage, c-spine fracture and aneurysm triage and include no perfusion product, while its aiOS platform orchestrates algorithms across a health system.
A 2026 scoping review put Aidoc against RapidAI and reported true positives of 78% versus 74%. The same review gave proximal LVO sensitivity as 78 to 97% across tools, weaker for distal and posterior occlusions. RapidAI's DUEL result, 98% of confirmed LVOs against Viz.ai's 73% over about 1,590 code strokes, is a retrospective single-center study that RapidAI promoted.
For a thrombectomy-capable stroke center that selects patients on perfusion, Aidoc is the weaker pick. A health system that wants stroke plus body CT triage under one vendor contract should look at Aidoc first.
