TORONTO – On average, radiology specialists diagnose fewer than 50% of cases of collapsed lung or pneumothorax using chest X-rays, said systems design engineer Hamid Tizhoosh. The Insignio system developed at Tizhoosh's Kitchener, Ontario-based Kimia Lab has gone further by identifying 75% of cases of collapsed lungs using artificial intelligence (AI) to search a database of 550,000 patients and compare 30,000 cases of pneumothorax there to X-rays of new patients with unknown conditions.
Singapore-based Vela Diagnostics Holding Pte. Ltd. has received U.S. FDA authorization via the de novo approval pathway for an in vitro diagnostic test to detect HIV-1 genomic drug resistance mutations (DRMs).
