  • O uso de Ferramentas Tecnológicas no Ensino Superior Moderno: abordagem integrada e perspectivas de aplicação em caso prático
    Publication . Vieira, Domingos; Costa, Pedro; Cunha, Lídia; Lemos, Joana; Ferreira, Sara; Metello, Luís F.
    A utilização de ferramentas tecnológicas no Ensino Superior como metodologia de ensino/aprendizagem apresenta-se cada vez mais generalizada. Consciente do facto, a Área Técnico-Científica de Medicina Nuclear da ESTSP.IPP, tem vindo a evoluir na integração gradual de algumas ferramentas tecnológicas na sua realidade específica quotidiana, sempre no sentido de aumentar a qualidade dos serviços que presta e a eficiência do processo, encarado na sua globalidade, acreditando na importante contribuição que podem vir a representar em termos de aumento da competitividade e da facilitação do alcance dos objectivos assumidos, particularmente em termos de ensino à distância e de internacionalização dos diversos projectos pedagógicos em que esta Área se encontra envolvida. Este trabalho tem como objectivo partilhar a experiência adquirida e o estado actual do uso de ferramentas tecnológicas no quotidiano, assim como os próximas etapas previstas no desenvolvimento de este projecto, considerado, por definição, como de longo-prazo. Serão apresentadas uma série de considerações, particularmente em termos da eficácia, inerentes à utilização quotidiana das várias ferramentas que foram já implementadas, sendo ainda tecidas uma série de recomendações e alertas, decorrentes da nossa experiência prática e potencialmente úteis aos que se estão a (ou pretendem) iniciar. O Espaço Europeu do Ensino Superior é declaradamente um desafio major para o qual temos que nos preparar da forma mais eficaz e competitiva, acreditando que a adopção de ferramentas tecnológicas – de uma forma atempada e sobretudo adequada aos objectivos específicos concretos de cada projecto pedagógico – pode vir a constituir um factor decisivo em termos do respectivo sucesso.

    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.
  • Preclinical Imaging: an Essential Ally in Modern Biosciences
    Publication . Cunha, Lídia; Horvath, Ildiko; Ferreira, Sara; Lemos, Joana; Costa, Pedro; Vieira, Domingos; Veres, Dániel S.; Szigeti, Krisztián; Summavielle, Teresa; Máthé, Domokos; Metello, Luís F.
    Translational research is changing the practice of modern medicine and the way in which health problems are approached and solved. The use of small-animal models in basic and preclinical sciences is a major keystone for these kinds of research and development strategies, representing a bridge between discoveries at the molecular level and clinical implementation in diagnostics and/or therapeutics. The development of high-resolution in vivo imaging technologies provides a unique opportunity for studying disease in real time, in a quantitative way, at the molecular level, along with the ability to repeatedly and non-invasively monitor disease progression or response to treatment. The greatest advantages of preclinical imaging techniques include the reduction of biological variability and the opportunity to acquire, in continuity, an impressive amount of unique information (without interfering with the biological process under study) in distinct forms, repeated or modulated as needed, along with the substantial reduction in the number of animals required for a particular study, fully complying with 3R (Replacement, Reduction and Refinement) policies. The most suitable modalities for small-animal in vivo imaging applications are based on nuclear medicine techniques (essentially, positron emission tomography [PET] and single photon emission computed tomography [SPECT]), optical imaging (OI), computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance spectroscopy imaging (MRSI), and ultrasound. Each modality has intrinsic advantages and limitations. More recently, aiming to overcome the inherent limitations of each imaging modality, multimodality devices designed to provide complementary information upon the pathophysiological process under study have gained popularity. The combination of high-resolution modalities, like micro-CT or micro-MRI, with highly sensitive techniques providing functional information, such as micro-PET or micro-SPECT, will continue to broaden the horizons of research in such key areas as infection, oncology, cardiology, and neurology, contributing not only to the understanding of the underlying mechanisms of disease, but also providing efficient and unique tools for evaluating new chemical entities and candidate drugs. The added value of small-animal imaging techniques has driven their increasing use by pharmaceutical companies, contract research organizations, and research institutions.
  • In the Way to ISO 9001:2008: Obtaining the Quality Certification in Public Higher Education
    Publication . Metello, Luís F.; Cunha, Lídia; Lemos, Joana; Lourenço, Leonel; Ferreira, Sara; Nogueira, Fábio; Vieira, Domingos; Pinto, Helena
    Quality Management in Higher Education is a rather complex and each day more challenging process. Nevertheless, it is believed to soon become the cornerstone for the development of modern Higher Education, so with an increasing role on Society itself; the clear assumption of this might be the – so needed - turning point in the relations between Academy and the “Real World”, helping to fill the gap.

  • Optimization of OSEM parameters in myocardial perfusion imaging reconstruction as a function of body mass index: a clinical approach
    Publication . Barros, Pietro Paolo de; Metello, Luis F.; Camozzato, Tatiane Sabriela Cagol; Vieira, Domingos
    Objective The present study is aimed at contributing to identify the most appropriate OSEM parameters to generate myocardial perfusion imaging reconstructions with the best diagnostic quality, correlating them with patients’ body mass index. Materials and Methods The present study included 28 adult patients submitted to myocardial perfusion imaging in a public hospital. The OSEM method was utilized in the images reconstruction with six different combinations of iterations and subsets numbers. The images were analyzed by nuclear cardiology specialists taking their diagnostic value into consideration and indicating the most appropriate images in terms of diagnostic quality. Results An overall scoring analysis demonstrated that the combination of four iterations and four subsets has generated the most appropriate images in terms of diagnostic quality for all the classes of body mass index; however, the role played by the combination of six iterations and four subsets is highlighted in relation to the higher body mass index classes. Conclusion The use of optimized parameters seems to play a relevant role in the generation of images with better diagnostic quality, ensuring the diagnosis and consequential appropriate and effective treatment for the patient.
