Radiation protection evaluations about a radiopharmaceutical production center based on a cyclotron
2012
Positron Emission Tomography (PET) has became a worldwide used functional and molecular imaging technique. Most of PET (or PET/CT- Computed Tomography) diagnostic facilities are installed within large population cities as well as dimensions of modern medical cyclotrons allow to install them inside hospitals or other health centers. Therefore, special radiation protection evaluations to assure safety operational conditions to operators and population are required. This work is focused on training activities oriented to evaluate PET/Cyclotron radiation protection procedures or to study special safety systems. The students are particularly oriented to determine shielding thickness according to…
Analysis of radionuclide concentration in air released through the stack of a radiopharmaceutical production facility based on a medical cyclotron
2015
Abstract Positron emitting radionuclides are increasingly used in medical diagnostics and the number of radiopharmaceutical production facilities have been estimated to be growing worldwide. During the process of production and/or patient administration of radiopharmaceuticals, an amount of these radionuclides might become airborne and escape into the environment. Therefore, the analysis of radionuclide concentration in the air released to the stack is a very important issue to evaluate the dose to the population living around the plant. To this end, sampling and measurement of radionuclide concentration in air released through the stack of a Nuclear Medicine Center (NMC), provided with a c…
Sentinel Node Identification in Melanoma: Current Clinical Impact, New Emerging SPECT Radiotracers and Technological Advancements. An Update of the L…
2020
Background: Melanoma is the most lethal skin cancer with a mortality rate of 262 cases per 100.000 cases. The sentinel lymph node (SLN) is the first lymph node draining the tumor. SLN biopsy is a widely accepted procedure in the clinical setting since it provides important prognostic information, which helps patient management, and avoids the side effects of complete lymph node dissection. The rationale of identifying and removing the SLN relies on the low probability of subsequent metastatic nodes in case of a negative histological exam performed in the SLN. Discussion: Recently, new analytical approaches, based on the evaluation of scintigraphic images are also exploring the possibility …
