The types of nuclear data and their quality required in the production   and application of diagnostic radionuclides are outlined. The   radioactive decay data determine the suitability of a radioisotope for    in vivo  tracer studies, both from the imaging and internal   radiation dose considerations. The nuclear reaction cross section data   allow optimisation of production routes. Both reactors and cyclotrons   are used for production purposes. The nuclear data needed in the two   cases and their present status are discussed. Special attention is   paid to radionuclides suitable for emission tomography (PET and   SPECT). The controversy about  reactor  vs  cyclotron    production of the widely used    99 Mo/ 99m Tc generator system is   discussed. Some special considerations in cyclotron production of   radionuclides are outlined. The need of accurate data near reaction   thresholds, the constraint of available particles and their energies   at a small cyclotron, the influence of increasing incident particle   energy, and the formation of isomeric impurities are discussed in   detail. The role of nuclear model calculations in predicting unknown   data is considered.
