- Assessing left ventricular dysfunction by the use of three distinct molecular imaging techniquesPublication . Reis, J.; Cunha, L.; Costa, Pedro; Neves, D.; Oliveira, T.; Ferrer-Antunes, A.; João, M. Faria; Metelo, Luís FranciscoLeft ventricular dysfunction might be assessed using distinct molecular imaging modalities. The most relevant are first pass radionuclide ventriculography (FPRV), multigated radionuclide angiography (MUGA) and gated blood-pool SPECT (GBPS) and are very often used for monitoring chemotherapy-related cardiomyopathy. This work aims to correlate these three molecular imaging techniques.
- Practices in radiopharmacy: Is the use of a breathing needle a concern on the radiochemical purity of 99mTc radiopharmaceuticals?Publication . Oliveira, M.; Oliveira, T.; Rebelo, A.; Sousa, C.; Silva, A.; Nery, J.; Amorim, I.; Castro, R.The action of collecting the patient’s individual doses isn’t subjected to any followed protocol, unlike most practices in the Nuclear Medicine department. In certain departments, the individual doses are withdrawn by perforating the rubber septum at every dose while others choose to keep a needle in the kit to avoid multiple perforations. Radiochemical purity is typically the primary concern for 99mTc-radiopharmaceuticals so the potential presence of impurities will affect the radiochemical stability of the radiopharmaceutical and, after being injected to a patient, result in an altered biodistribution and poor image quality. Therefore, it’s important to verify every practice used on the product, which results in a need to learn if the needle kept in the kit at some departments is affecting the radiopharmaceutical’s stability. It is aimed to disseminate the results obtained on a large study performed to evaluate whether there is any correlation between keeping the needle in the kit, during the clinical practice and during the stability period of two different radiopharmaceuticals.
- Prevalência de obesidade e fatores de risco em estudantes da ESTSPPublication . Noites, Andreia; Oliveira, T.; Mota, MS.; Amorim, M.; Couto, M.A obesidade é definida pela Organização Mundial de Saúde como um acúmulo anormal ou excessivo de gordura corporal que pode atingir graus capazes de afetar a saúde. Em Portugal afeta 53,6% da população. É uma doença multifatorial associada ao risco aumentado de comorbilidades e responsável por elevados custos diretos e indiretos.
