Minimisation of equivalent dose to the extremities during PET radiopharmaceuticals dispensing
| Resumo: | Positron Emission Tomography-Computed Tomography (PET/CT) has emerged as an early diagnosis and staging in several pathologies, particularly on cancer. The radiopharmaceuticals used in this technique are beta plus-emitters (β+) and radiate gamma photons (γ) with 511 keV, which is considerably higher in comparison with conventional nuclear medicine, implying that the conventional amounts of lead and tungsten in shields are not enough for an appropriate radiation protection of the practitioners. In this work, two commercially available PET radiopharmaceuticals (PET-Rph) dispensers are compared. Results demonstrate that both instruments are robust and accurate, although not precise. Also, particular care needs to be taken while working with PET-Rph, namely the arrangement of the material and equipment on the working bench. |
