Chemistry and Concept for an Automated 72Se/72As Generator
The growth of positron emission tomography (PET), with its unique capability to image function as well as structure, depends very much on the availability of positron emitting radioisotopes. Arsenic-72 is a radionuclide possessing significant potential as a PET radioisotope. A wide variety of bone, brain, and tumor seeking agents can be labeled with 72As. A 72Se/72As radiochemical generator would allow on-site recovery of high specific activity 72As for PET research and applications. We have developed a reliable, simple separation chemistry which could be neatly automated for a safe, easy-to-use generator.
