A Canadian study comparing the properties of the technetium-99m isotope produced from a cyclotron with that produced from a generator found that they were comparable in terms of scintigraphic images and distribution patterns in animals. "This research provides a near-term solution for the medical isotope shortage and the associated global interruptions of molybdenum-99 supply, the high costs of reactor maintenance, radioactive waste processing and eventual reactor decommissioning," the lead author of the study said. However, more large-scale studies need to be undertaken before full-scale cyclotron-based production of Tc-99m could be initiated, the researchers said.
