- 3D printing of abdominal immobilization masks for therapeutics: dosimetric, mechanical and financial analysisPublication . Duarte, Jessica; Loja, Maria Amélia Ramos; Portal, Ricardo; Vieira, Lina OliveiraMolding immobilization masks is a time-consuming process, strongly dependent on the healthcare professional, and potentially uncomfortable for the patient. Thus, an alternative sustainable automated production process is proposed for abdominal masks, using fused deposition modelling (FDM) 3D printing with polylactic acid (PLA). Radiological properties of PLA were evaluated by submitting a set of PLA plates to photon beam radiation, while estimations of their mechanical characteristics were assessed through numerical simulation. Based on the obtained results, the abdominal mask was 3D printed and process costs and times were analyzed. The plates revealed dose transmissions similar to the conventional mask at all energies, and mechanical deformation guarantees the required immobilization, with a 66% final cost reduction. PLA proved to be an excellent material for this purpose. Despite the increase in labour costs, a significant reduction in material costs is observed with the proposed process. However, the time results are not favorable, mainly due to the printing technique used in this study.
- Anxiety experienced by oncological patients who undergo 18F-FDG PET CT: a systematic reviewPublication . Vieira, Lina Oliveira; Pires, A.; Grilo, Ana MonteiroIntroduction: Anxiety is an emotional reaction often experienced by patients who undergo Positron Emission Tomography/Computed Tomography (PET/CT) with 18F-2-fluoro-2-deoxy-d-glucose (18F-FDG). This systematic review aimed to summarise the evidence currently available considering the anxiety experienced by adult oncological patients concerning pre and post 18F-FDG PET/CT examination and the factors contributing to anxiety. Methods: A systematic review search of CINAHL, PsycINFO, PubMed, Scopus, and Web Science databases and other manual search sources, was conducted from November to February 2021. The research included articles published from January 2000 to December 2020. It included quantitative studies, which analyzed the anxiety experienced by oncological patients who had undergone 18F-FDG PET/CT. Results: Ten articles met the inclusion criteria for this systematic review. The studies selected were published between 2011 and 2020 and carried out in five countries. Anxiety experienced by patients was evaluated at the various stages of the 18F-FDG PET/CT, eight studies assessed it in the pre-examination, seven studies in the post-examination, and five studies at both times. Four main anxiety factors were found: patients' clinical situation, first-time patients’ examination, scan procedure, and patients' concern with the examination result. Conclusion: Moderate to high levels of anxiety are present in most of the patients who undergo the examination. This review also highlights several factors related to the anxiety levels through different procedure moments. Implications for practice: The results of this research will allow health professionals to adjust non-pharmacological strategies to decrease anxiety levels in oncological patients undergoing 18F-FDG PET/CT.
- Effects of a music-based intervention on psychophysiological outcomes of patients undergoing medical imaging procedures: a systematic review and meta-analysisPublication . Vieira, Lina Oliveira; Carvalho, Catarina; Grilo, Ana; Reis, Jaime; Pires, Ana Filipa; Pereira, Edgar; Carolino, Elisabete; Almeida-Silva, MarinaIntroduction: Musical intervention (MI) is a valuable strategy for addressing the psychological and emotional challenges faced by patients undergoing imaging procedures. This study explores MI's impact on psychophysiological outcomes during imaging procedures, detailing the sound repertoire and technical characteristics employed in MI. Methods: A systematic review (SR) and meta-analysis (MA) were conducted. Electronic database searches of PubMed, Web-of-Science, and Scopus were performed encompassing original randomised research and quasi-experimental articles published until June 2023. Results: Thirteen articles were included in this SR, scoring between 23 and 68 on the Joanna Briggs Institute (JBI) Checklist. Four articles were included to perform a MA concerning anxiety and heart rate (HR) outcomes. Most studies utilised digital playlists as the medium for MI. Headphones were commonly used, with an average volume of 50-60 dB and a musical frequency of 60-80 beats/min. While authors generally preferred selecting musical genres for the repertoire, two articles specifically chose Johann Pachelbel's "Canon in D major" as their musical theme. In terms of psychological parameters, the experimental groups exhibited lower anxiety values than the control groups, with further reductions after MI. However, MA shows that this trend is only marginally significant. Patient comfort and overall examination experience showed improvement with MI. Regarding physiological parameters, HR, especially in the final phase of the examination, was significantly lower in the experimental group compared to the control group. Conclusion: Across multiple studies, MI demonstrated the ability to reduce anxiety and HR. However, no specific music repertoire emerged as the most effective. Implications for practice: MI arises as a painless, reliable, low-cost, and side-effect-free strategy, presenting imaging departments with a practical means to enhance patient comfort and mitigate anxiety and stress during medical procedures.
- Potential benefits of social media in educating healthcare professionals and students on medical imaging with ionizing radiation: a scoping reviewPublication . Vieira, Lina Oliveira; Kang, C.; Martins, M.; Grilo, AnaIntroduction: Advancements in medical imaging with ionizing radiation have significantly transformed the field and enhanced the education and training of medical professionals. A notable development in this educational landscape is the use of social media, which engages millions of users worldwide. This scoping review aims to explore the potential of social media as an educational tool for healthcare professionals and students in medical imaging with ionizing radiation, highlighting its benefits and disadvantages. Methods: In March 2024, research was conducted on three databases: PubMed, Scopus, and Web of Science. The research equation combined the terms "Social Media," "Education," and "Medical Imaging." Data extraction was based on PRISMA-ScR guidelines for scoping reviews. Results: Seventeen articles published between 2017 and 2023 were included in this review, all of which were descriptive cross-sectional studies and primarily focused on popular platforms such as Twitter, Facebook, and YouTube. The key advantages of social media use for medical imaging education were accessibility, ease of use, and broad reach, while the main limitation was the potential for misinformation. Conclusion: While there is clear potential to integrate social media into medical imaging education, more must be done to understand their effectiveness. This ongoing process requires the active engagement of all stakeholders. While promising, further research is needed to validate social media as an educational tool. Implications for practice: Successfully integrating social media into medical imaging education, thus enhancing learning, communication, and collaboration between healthcare professionals, requires a strong commitment to managing accurate and reliable content sources on social media.
