Abstract
In the last few decades, advances in molecular imaging technologies have had a major
impact on many aspects of healthcare. In particular, radiohalogenated compounds have
been used for non-invasive visualization of human anatomy, for the diagnosis of disease
and in drug development programs. As a consequence of these advances, a range of novel
synthetic radiochemical methods have been reported that allow more effective and efficient
radiohalogenation from a broader range of precursors. In developing new radiochemical
methods, special requirements are required to optimize the incorporation of highly
radioactive, short-lived, isotopically labelled reagents. This article highlights
the key practical considerations and challenges encountered when utilizing the most
commonly used radiohalogens in nuclear medicine.
