Mo-99 is used to produce Technetium-99 metastable (Tc-99m), one of the most prevalently used diagnostic imaging agents in nuclear medicine, which helps detect illnesses like cancer and heart disease. Tc-99m is delivered to radiopharmacies and hospitals across North America to make radiopharmaceuticals for patients.
Re-establishing a reliable supply of Mo-99 is critically important for the 40 million patients a year who undergo Tc-99m based SPECT scans to diagnose life-critical diseases. To address this supply shortage, Curium was forced to reroute, adjust, and in some cases postpone customer orders, with production capacity for some cyclotron …
