Michael Walter reports that the University of Missouri Research Reactor (MURR) in Columbia has announced it is the first domestic supplier of Iodine-131 (I-131), a radioisotope used to diagnose and treat thyroid cancer and hyperthyroidism, in the last 30 years. “Supplying I‑131 is part of a strategic initiative by the University of Missouri and MURR to address medical isotope shortages and further the University’s research mission,” David Robertson, executive director of MURR, said in a news release from the University of Missouri. MURR, a part of the school for more than 50 years, is also a supplier of Therasphere, Quadramet and Lutathera, which was recently approved by the FDA to help treat pancreatic cancer patients, according to the news release.
