[Current problems of medical physics in the radionuclide diagnosis].

The most important problems of medical physics in clinical radionuclide diagnosis are considered on the basis of the data available in the literature. The matter and trends in the development of investigations, into radiopharmaceutical, hard- and software, methodological, and algorithmic supports of radionuclide diagnosis, as well as those into its quality insurance and provision of radiation safety of patients and the personnel are also analyzed.
