With improved reliability, artificial intelligence algorithms that detect COVID-19 from a chest x ray could help clinicians triage patients. The developers of AI algorithms hope to help doctors better distinguish COVID-19 from other lung infections in chest x rays. Chest x rays offer a quick screening method for lung problems: A collapsed lung, the buildup of excess fluid, or swollen tissue are all recognizable by radiologists in these black and white images. Doctors also use the images to help quickly diagnosis diseases, such as pneumonia.
Making x-ray screening of COVID-19 similarly speedy would benefit over-run hospitals, and the developers of artificial intelligence (AI) algorithms are hoping that they can help. But getting the data they need from hospitals and ensuring accuracy are challenges that they must first overcome.
