The work presented describes the main ways of preparing radiopharmaceuticals and carrying out nuclear-medical examinations in pediatric patients. Through the differences in the execution of the tests, the importance of dosimetry is revealed, i.e. the diagnostic reference levels, in which the percentage of activity that must be administered to the child on the basis of that introduced in the adult is indicated.
Through a study performed on pediatric patients, subjected to nuclear-medical investigations, the validity of the LDRs is reported according to the scheme in tab. 6 (EANM-EUROPEAN ASSOCIATION OF NUCLEAR MEDICINE).
Through a study conducted in pediatric patients, subjected to medical - nuclear investigations, the importance of the dose is noted in order to obtain greater benefits in the patient and high quality images for diagnostic purposes. By carrying out pediatric-radiopharmaceutical calculations, it is possible to reproduce the aforementioned, ie an optimization of the dose.
