This timely resource compares single-photon emission tomography (SPECT) used mainly withTechnetium and iodine for routine clinical examinations and positron emission tomography(PET) employing short-lived radionuclides of carbon oxygen nitrogen and fluorine in researchinvestigations. Presenting the logic behind why one approach is better than another in various circumstancesRadio pharmaceuticals details the use of radiolabelled substrates in measuring the effect of diseaseand drugs on regional metabolism and receptor concentration/occupancy. discusses factorsaffecting the selective retention of small metal complexes by various tissues. analyzes the interactionof small exogenous metal complexes with enzymes in vivo and the critical role of stereochemistry. explores the use of radio labelled compounds in the study of neuroactive compoundsneurotransmitters enzyme inhibitors and substrates in vivo. covers the design and pharmacologyof radiolabelled drugs as probes of site of action selectivity and specificity and pharmacokineticsin vivo. and more.
