Hospitals and medical facilities around the globe are rationing intravenous (IV) contrast imaging procedures. The U.S. Food and Drug Administration has reported shortages of two forms of contrast medium fluids known as Iohexol and Iodixanol, both commonly used in CT scans. GE Healthcare, manufacturers of the products, advised that the shortage was due to a lockdown and subsequent temporary shutdown at a production facility in China. The shortage is forcing physicians to reserve the limited supply of IV contrast material for life or death scenarios.
