Bispidines (3,7-diazabicyclo[3.3.1]nonane) and their derivatives act as bifunctional chelators (BFC), combining the advantages of multidentate macrocyclic and acyclic ligands e.g. high kinetic inertness, rapid radiolabelling under mild conditions. This bicyclic chelator system shows a great diversity in terms of its denticity and type of functional groups, yielding a wide range of multidentate ligands that can bind a variety of different metal ions. In addition, they allow a facile functionalisation of targeting molecules such as peptides, peptidomimetics, and bispeci􀄀c antibodies. Herein, examples of various bispidine complexes labelled with [64Cu]Cu2+, [111In]In3+, [ 177Lu]Lu3+ or [ 225Ac]Ac3+ will be presented which provide a picture of how different substituents in􀄁uence the coordination mode. Target-speci􀄀c radiolabelled bispidine-based conjugates (e.g. peptides, antibody fragments, antibodies) investigated in vivo by positron emission or single-photon emission computed tomography will be presented and discussed in terms of their suitability for nuclear medicine applications.

Magnetic Particle Imaging (MPI) is a new non-invasive imaging technique with significantly increased sensitivity over MRI and faster acquisition times than PET and MRI. The MPI capability at the Alfred Research Alliance - Monash Biomedical Imaging site in Melbourne, Australia, is the world’s first MPI system with Computed Tomography (CT) and Hyperthermia capabilities. It provides unique capabilities that open the door to cutting-edge opportunities for interdisciplinary projects in medical research, chemistry and biotechnology. The webinar will involve: * official launch of Magnetic Particle Imaging at Monash University * the MPI system supplier, Magnetic Insight, discussing the world first technology and its potential * presentations from key researchers outlining MPI applications and the benefits of utilising the technology.
