TB screening stops waiting for a radiologist: across about 40 sites in six countries, reading time falls from weeks to under 45 seconds
Tuberculosis still kills an estimated 1.23 million people a year, and high-burden regions lack the radiologists who read chest X-rays. Google Research and Google for Health handed its chest X-ray algorithms to Pretoria-based Nexus AI, which turned them into a CE-certified clinical diagnostic tool now deployed in about 40 healthcare facilities across six countries including South Africa, Sierra Leone and Côte d'Ivoire. More than 90 clinicians have evaluated over 25,000 chest radiographs, cutting turnaround from weeks to under 45 seconds for rapid triage, with final clinical decisions left to health workers.
