Abstract:
Yttrium-86 is a non-standard positron emitter that can provide dosimetry information prior to therapy with yttrium-90 radiopharmaceuticals and be used to follow biochemical processes. In this chapter, we discuss the production, purification and applications of 86Y for PET imaging. More specifically, 86Y radiolabeling is highlighted and protocols to determine the radiochemical purity of 86Y-DOTA and 86Y-DTPA are presented.
