AI tool uses chest X-ray to differentiate worst cases of COVID-19: Study ANI | Updated: May 12, 2021 16:28 IST New York [US], May 12 (ANI): A computer program that has been trained to see patterns by analysing thousands of chest X-rays --predicted with up to 80 per cent accuracy which COVID-19 patients would develop life-threatening complications within four days, a new study finds. Developed by researchers at NYU Grossman School of Medicine, the program used several hundred gigabytes of data gleaned from 5,224 chest X-rays taken from 2,943 seriously ill patients infected with SARS-CoV-2, the virus behind the infections. The authors of the study, publishing in the journal npj Digital Medicine online, cited the "pressing need" for the ability to quickly predict which COVID-19 patients are likely to have lethal complications so that treatment resources can best be matched to those at increased risk. For reasons not yet fully understood, the health of some COVID-19 patients suddenly worsens, requiring intensive care, and increasing their chances of dying.
