Mamografia Espectral de Contraste

Abstract

A mamografia de contraste é uma aplicação recente possível com a mamografia digital directa, que utiliza contraste iodado endovenoso tendo como princípio a neovascularização induzida no cancro da mama, permitindo obter informação morfológica e funcional. Na mamografia espectral de contraste realiza-se uma aquisição simultânea com alta e baixa energia para cada incidência após administração de contraste iodado endovenoso. É depois feita uma imagem recombinada em que são realçadas as áreas que captam contraste. As potenciais aplicações desta técnica são o esclarecimento de lesões equívocas na mamografia, a deteção de lesões em mamas densas, a avaliação da extensão das lesões e da recorrência tumoral, podendo ter um papel determinante em doentes que não podem realizar ressonância magnética.
