Resumo: | Abstract Computed tomography is one of the diagnostic imaging methods that contributes to the radiation dose received by patients. The present study seeks to evaluate the implication of the exposure parameters in the radiation dose received by the patient in Computed Tomography exams at Leiria Hospital Center, establishing a comparison with the Diagnostic Reference Levels presented by the European Guidelines. The optimization of the protocols used and the definition of the local Diagnostic Reference Levels must be applied, according to the principles of radiological protection in accordance with the national legal framework in force. This work carried out within the scope of the internship of the Training Course in Radiological Protection and Radiological Safety - Level 2, in the field of medical activities, aims to harmonize the dose values of the most frequent Computed Tomography exams, performed on standard adult patients in the Imaging Service of, Leiria Hospital Center analyzing the respective protocols and descriptors of weighted Computed Tomography Dose Index and Product Dose Length. To help with the analysis of results, an Excel spreadsheet was used for data collection and data processing. The most frequent exams and the selected clinical information were: Cranium – Stroke and Trauma; Chest - Covid Pneumonia and Pulmonary Thromboembolism; and Thorax/Abdomen/Pelvic -Staging and Follow-Up. It was concluded that the values of the Diagnostic Reference Levels for Cranium – Stroke/Trauma, Thorax – Pneumonia and Thorax/Abdomen/Pelvic – Follow-Up are below the reference values, contrary to the values obtained for Chest/Abdomen/Pelvic – Staging that is slightly above and towards Chest – Thromboembolism is elevated. In these last two exams, the procedures and protocols will be analyzed, in order to evaluate the implementation of possible corrective actions for dose optimization. |

O presente estudo procura avaliar a implicação dos parâmetros de exposição na dose de radiação recebida pelo paciente em exames de Tomografia Computorizada no Centro Hospitalar de Leiria, estabelecendo a comparação com os Níveis de Referência de Diagnóstico apresentados pelas Guidelines Europeias. A otimização dos protocolos utilizados e a definição de os Níveis de Referência de Diagnóstico locais devem ser aplicadas, segundo os princípios da proteção radiológica de acordo com o quadro legal nacional em vigor. Este trabalho realizado no âmbito do estágio do Curso de Formação em Proteção Radiológica e Segurança Radiológica – Nível 2, no domínio das atividades médicas, tem como objetivo a harmonização dos valores de dose dos exames mais frequentes de Tomografia Computorizada, realizados a pacientes adultos padrão no Serviço de Imagiologia do Centro Hospitalar de Leiria, analisando os respetivos protocolos e descritores de Índice de Dose em Tomografia Computorizada ponderado e Produto Dose Comprimento. Para auxiliar a análise de resultados, utilizou-se uma folha de cálculo de Excel para recolha de dados e para o tratamento de dados. Os exames mais frequentes e as informações clínicas selecionados, foram: Crânio-Encefálico – Acidente Vascular Cerebral e Traumatismo; Tórax - Pneumonia por Covid e Tromboembolismo Pulmonar; e Tórax/Abdómen/Pélvico -Estadiamento e Follow-Up. Concluiu-se que os valores de os Níveis de Referência de Diagnóstico para o Cranio – Acidente Vascular Cerebral /Traumatismo, Tórax – Pneumonia e Tórax/Abdómen/Pélvico – Follow-Up se encontram abaixo dos valores de referência, ao contrário dos valores obtidos para Tórax/Abdómen/Pélvico – Estadiamento que se encontra ligeiramente acima e para Tórax – Tromboembolismo se encontra elevado. Nestes dois últimos exames serão analisados os procedimentos e protocolos, no sentido de avaliar a implementação de possíveis ações corretivas de otimização de dose.NUCLIRAD - Núcleo de Desenvolvimento dos Técnicos de Radiologia2023-07-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.46885/roentgen.v4i2.110https://doi.org/10.46885/roentgen.v4i2.110ROENTGEN-Scientific Journal of Radiological Techniques; Vol. 4 No. 2 (2023): Innovations impacting Radiology; 66-74ROENTGEN-Revista Científica das Técnicas Radiológicas; v. 4 n. 2 (2023): Inovações com impacto na Radiologia; 66-742184-7657reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://roentgen.pt/index.php/Principal/article/view/110https://roentgen.pt/index.php/Principal/article/view/110/89Direitos de Autor (c) 2023 ROENTGEN-Revista Científica das Técnicas Radiológicasinfo:eu-repo/semantics/openAccessCastanheira, Clara2023-12-20T16:17:15Zoai:roentgen.pt:article/110Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T00:55:21.741870Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
