Resumo: | Introduction – Myocardial perfusion imaging (MPI) is a widely accepted study applied in the diagnosis and follow-up of coronary artery disease. Interpretation of myocardial perfusion images requires visual analysis of the reconstructed slices. The color scale selected can have a significant effect on the final appearance of the image and on the clinical interpretation of myocardial perfusion. Aim – Evaluate the influence of the color scale in the qualitative analysis of MPI and study which one should be preferably used for visual interpretation of myocardial perfusion. Methods – Thirty-five MPI studies were visually interpreted by 16 nuclear medicine technologist students in the following color scales: Cool, Gray, Gray Invert, Thermal and Warm. Visual analysis of Cool’s color scale relied on a semi-quantitative scoring system. The remaining color scales were evaluated by comparison with Cool. Results/Discussion – For Cool’s color scale, inter-operator variability has shown statistically significant differences among all the participants (p<0.05), which can be assigned to the subjectivity of the visual evaluation. The results obtained for Gray and Gray Invert colors scales were the closest for the myocardial perfusion observed with Cool, being alternative color scales suited for this purpose. Regarding Thermal and Warm color scales the results were divergent, showing that they are not the optimal choice for myocardial perfusion interpretation. Conclusion – The color scale selected can influence the qualitative assessment of MPI. |

A escala de cores selecionada é essencial na interpretação clínica das imagens de perfusão do miocárdio. Objetivo – Avaliar a influência de diferentes escalas de cores na avaliação qualitativa das imagens de CPM e estudar quais as mais adequadas para análise visual. Métodos – Trinta e cinco estudos de CPM foram avaliados visualmente por 16 estudantes da licenciatura em medicina nuclear nas escalas de cores Cool, Gray, Gray Invert, Thermal e Warm. Para a escala de cores Cool, a análise das imagens de CPM foi realizada através de um sistema de classificação semiquantitativo por scores. As restantes escalas de cores foram avaliadas por comparação com a análise das imagens efetuada com escala de cores Cool. Resultados/Discussão – Para a escala de cores Cool, a variabilidade interoperador revelou a existência de diferenças estatisticamente significativas entre todos os participantes (p<0,05), o que se pode atribuir à subjetividade da avaliação visual. Os resultados relativos às escalas de cores Gray e Gray Invert foram os mais próximos da perfusão do miocárdio observada com a escala Cool, considerando-se escalas de cores alternativas na análise visual dos estudos de CPM. Para as escalas de cores Thermal e Warm os resultados foram mais divergentes, não se considerando adequadas para a avaliação visual dos estudos de CPM. Conclusão – A escala de cores influencia a avaliação qualitativa da perfusão na CPM.Escola Superior de Tecnologia da Saúde de Lisboa (Instituto Politécnico de Lisboa)2022-08-25info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25758/set.1391oai:journals.ipl.pt:article/576Saúde e Tecnologia; No. 15 (2016): Maio 2016; 19-27Saúde & Tecnologia; N.º 15 (2016): Maio 2016; 19-271646-9704reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.ipl.pt/stecnologia/article/view/576https://doi.org/10.25758/set.1391https://journals.ipl.pt/stecnologia/article/view/576/503Direitos de Autor (c) 2022 Saúde & Tecnologiainfo:eu-repo/semantics/openAccessFigueiredo, AndreiaRamos, EmíliaCarolino, ElisabeteVaz, TâniaVieira, Lina2022-12-20T10:58:57Zoai:journals.ipl.pt:article/576Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:21:23.753699Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
