The focus of this new book is for medicinal chemists on the chemical agents that have been used, or might be required in the future, and the methods of synthesis for inserting the reporter groups. Medicinal chemists need to know the critical issues involved in using such chemical agents with regard to the biological applications - for instance - what properties are needed chemically and why? The topics covered in the book are: PET, SPECT, contrast agents, radioimaging/radionuclide conjugates, receptor mapping, small animal imaging (eg. WBAR - whole body autoradiography); photoinduced labelling, as well as chapters on the physical techniques used including: NMR, mass spectrometry and Xray. A key reference for academics, postgraduates, researchers, industrialists and professionals working in or joining this field.
