Lunit vs RapidAI
Lunit reads breast and chest images, RapidAI reads stroke and vascular CT, and the two reach different readers. RapidAI has seven K-numbers on record from 2013 to 2024, an LVO module the vendor puts at 97% sensitivity and 96% specificity, and an enterprise license with no public price. One AJNR study found its CT perfusion volumes are not interchangeable with Viz.ai's. A stroke service sizing a CT-based pathway gets its answer in Rapid ICH, ASPECTS and LVO. Lunit has five breast records for INSIGHT MMG and DBT, the newest decided in April 2026, plus INSIGHT CXR Triage for chest X-ray. A breast screening unit running 2D and tomosynthesis reads has the Lunit option, and a chest X-ray service that wants triage can add it, with the price available only through a contact form.
