- Study of the Influence of Patient Hydration in Bone ScintigraphyPublication . Ferreira, Sara; Cunha, Lídia; Osório, Soraia; Matias, Mariana; Lemos, Joana; Vieira, Domingos; Soares, Sofia; Fonseca, Abigaíl; Silva, José Alexandre; Amorim, Inês; Castro, Rosa; Metello, Luís F.The bone scintigraphy is a diagnosis method noninvasive and sensitive in detecting early bone lesions, constituting about 35% of all tests performed in the Service of Nuclear Medicine, of the Hospital of Santo Antonio, in the city of Porto, where the following study took place. One of the important technical details in preparing the patient for this examination is the hydration following the administration of the radiopharmaceutical. The aim of this study focused on assessing the value of hydration on the quality of the image in a bone scintigraphy.
- Study of the influence of patient hydration in bone ScintigraphyPublication . Ferreira, S.; Cunha, L.; Fonseca, A.; Vieira, Domingos; Lemos, Joana; Matias, M.; Osorio, S.; Soares, S.; Silva, J. A.; Amorim, M. I.; Castro, R.; Metelo, Luís FranciscoBone Scintigraphy is a noninvasive and very sensitive Nuclear Medicine diagnostic method in detecting early bone lesions. Between the important technical details to consider when dealing with patient preparation there is the hydration level.
- Motion correction software in Myocardial Perfusion Imaging: is it useful?Publication . Cunha, L.; Lamego, J.; Ferreira, S.; Lemos, Joana; Vieira, Domingos; Fonseca, A.; Pires, L.; Neves, D.; João, M. Faria; Pereira, L.; Moreira, A. S.; Metelo, Luís FranciscoMyocardial Perfusion Imaging (MPI) is a very important tool in the assessment of Coronary Artery Disease (CAD) patients and worldwide data demonstrate an increasingly wider use and clinical acceptance. Nevertheless, it is a complex process and it is quite vulnerable concerning the amount and type of possible artefacts, some of them affecting seriously the overall quality and the clinical utility of the obtained data.
- Parameters optimization of filtered back projection in Myocardial Perfusion Imaging reconstructionPublication . Metelo, Luís Francisco; Cunha, L.; Vieira, Domingos; Fonseca, A.; Tavares, A.; Soares, S.; Amorim, I.; Castro, R.; Abrantes, A. M.; Botelho, M. F.Nowadays, even if it is noticed an increasingly wider use of Iterative Methods (IM), a significant number of NM Departments is still routinely using Filtered Backprojection (FBP) as the method of choice in what concerns image processing in MPI. Several authors recommend the use of same filter parameters, no matter what the patient physical characteristics are.
