Basic Premises to Molecular Imaging and Radionuclide Therapy - Part 1

This manuscript is a complementary article to an accompanying paper, published in a forthcoming issue, which will give an overview on the central role of chelation in labelling radiocompounds; either for imaging and/or for radionuclide therapy. In order to facilitate a better understanding of the importance of Chelator-Based Imaging & Therapy, we will briefly discuss in this publication - which is partially intended as an introduction to the second paper - which contains the major basic principles of molecular imaging and radionuclide therapy. Although these issues are of interest in the general field of Nuclear Medicine; since the chelation process involves the labelling with radiometals; we aim to highlight examples of this category in this paper which concern this class of nuclides in this particular issue.
