The U.S. Food and Drug Administration has widened its investigation into radiation overdoses that patients have received from a type of brain scan, announcing that it was looking into possible overdoses at Providence St. Joseph Medical Center in California and a hospital in Alabama. Providence St. Joseph is now the third hospital in Los Angeles County under investigation for problems with CT brain perfusion scans. Unlike the other cases, which involved scanners made by General Electric, the scanner at Providence St. Joseph was made by Toshiba.
