4. Scientific meeting of the Brazilian Society of Nuclear Biosciences. Program and abstracts

Utilization of radioisotopes and radiopharmaceuticals in nuclear medicine is reported including production and purification aspects. Quality control, quality assurance, feasibility studies and process reliability are emphasized. Biodistribution and biological pathways are studied by radioassay, tracer techniques, radionuclide kinetics, scintiscanning and labelled compounds (mainly Technetium99m). In vivo and dynamic function studies are presented in animals (e.g. rats, mice and habits). Diagnostic techniques, case reports of several diseases are presented. Radiation monitoring, radiation dose distribution, dosimetry, safety procedures, personnel monitoring are discussed. Application of medicinal plants and their effects on blood elements is studied. Legal issues regarding to licensing regulations, nuclear trade, operating licenses and licensing procedures are mentioned. Historical aspects in nuclear medicine and the use of radioisotopes are briefly reported
