From Our Perspective: FDA’s Role in Helping a Critical Medical Isotope Meet Sufficient Supply in the US for First Time

By: Joseph Rajendran, M.D. (Medical Doctor), FASNC (Fellow of the American Society of Nuclear Cardiology), FACNM (Fellow of the American College of Nuclear Medicine), Medical Officer, FDA (U.S. Food and Drug Administration), CDER (Center for Drug Research and Evaluation), OND (Office of New Drugs), OSM (Office of Specialty Medicine), DIRM (Division of Imaging and Radiation Medicine)

Mo-99 is an important radioactive isotope used in medical imaging to detect cancer and other potentially fatal conditions.
