[en] In nuclear medicine, the prescriptions of isotopic investigations are increasing because they can provide early information about morphological anomalies and permit,so to avoid long and onerous treatments. Until now, Morocco imports the radiopharmaceuticals in spite of the difficulties related to administrative procedures. To facilitate these procedures CNESTEN has launched a project which involves the following activities: - Import and distribution of needed radiopharmaceuticals; - development and production of new radiopharmaceutical kits in cooperation with scientific partners. Priority is given to the most prescribed radiopharmaceuticals. Many kits have been produced with manufacturing protocol modifications aiming to improve and optimize the production processes. The quality of the obtained products is tested and their biodistribution kinetics are studied. (F.M.)
