The chief executive of America's largest public hospital system says he is prepared to start replacing radiologists with artificial intelligence in some circumstances, once the regulatory landscape catches up. 

Mitchell H. Katz, MD, president and CEO of NYC Health + Hospitals, recently spoke during a panel discussion held by Crain's New York Business. The trained internal medicine specialist noted how AI is increasingly being used to interpret mammograms and X-rays. 

This presents an opportunity to save on how much hospitals spend on radiologists, who have become more costly amid rising demand for imaging, Crain's reported Thursday. 

"We could replace a great deal of radiologists with AI at this moment, if we are ready to do the regulatory challenge," Katz said at the forum, held on March 25.
