Protocolos e valores de doses em procedimentos de Fluoroscopia por Tomografia Computadorizada

Abstract

Este trabalho tem como objetivo destacar os protocolos que são utilizados para procedimentos de Fluoroscopia por Tomografia Computadorizada (FTC) por meio de uma revisão bibliográfica. Foi apresentada uma breve discussão sobre a importância das imagens produzidas por raios X e a evolução da sua utilização, como na técnica de Tomografia Computadorizada (TC). Também, foram apresentados os conceitos sobre a FTC, os principais procedimentos que a utilizam e suas vantagens e desvantagens. Para este trabalho foi feita uma pesquisa em várias plataformas de busca. Realizou-se um estudo dosimétrico referente às doses de radiação recebidas pelo paciente e os profissionais nos diferentes protocolos de varredura dos procedimentos de FTC, certificando os princípios da proteção radiológica, como o quisito ALARA. Após a seleção dos parâmetros de interesse, foi feita uma tabela para uma melhor comparação dos protocolos utilizados e as doses envolvidas. Analisou-se que os profissionais e pacientes durante os procedimentos de FTC estão expostos à uma dose alta radiação, mas estudos vêm sendo feitos para redução das doses, empregando equipamento de proteção individual (EPI) e a posição do médico radiologista.
