Lunit vs Viz.ai

Lunit reads breast and chest images. Its 510(k)s cover INSIGHT MMG for mammography, INSIGHT DBT for tomosynthesis (version 1.2 decided in March 2026) and INSIGHT CXR Triage for chest X-ray. Volpara density and positioning tools now sit under the Lunit name. Lunit fits a breast imaging center running screening mammography first and a radiology group with a long chest X-ray queue second. An independent PLOS Digital Health comparison found a newer INSIGHT CXR version less accurate for TB reading until its threshold was recalibrated.

Viz.ai is a coordination platform for stroke and vascular teams. ContaCT received De Novo authorization for large vessel occlusion triage on CTA, and the vendor says Viz is embedded in 2,000 hospitals. Alerts reach clinicians through a mobile app and group messaging, which fits regional stroke programs that transfer patients between hospitals. Viz HCM also holds a De Novo authorization, next to 510(k)s for Viz ICH and Viz CTP.

Nobody weighs these two against each other. Breast and chest reading rooms buy one, and stroke and cardiac transfer teams buy the other.
