PET\/CT (Tomografia por Emiss\u00e3o de Positr\u00f5es) na Southcoast Health<\/strong><\/h2>\n

A PET\/CT \u00e9 um exame imagiol\u00f3gico indolor. Utiliza um medicamento radioativo (chamado marcador) para mostrar o funcionamento dos \u00f3rg\u00e3os e tecidos e utiliza a TAC para mostrar os \u00f3rg\u00e3os internos. Isto difere de outros exames imagiol\u00f3gicos que apenas mostram a estrutura dos \u00f3rg\u00e3os e tecidos.<\/span><\/p>\n

Porque \u00e9 que \u00e9 realizado<\/b><\/h2>\n

Os nossos m\u00e9dicos da Southcoast Health pedem exames PET\/CT para diagnosticar ou avaliar doen\u00e7as, incluindo <\/span>perturba\u00e7\u00f5es cerebrais<\/span>, <\/span>cancro<\/span> e <\/span>problemas card\u00edacos<\/span>.<\/span><\/p>\n

A PET pode muitas vezes detetar a doen\u00e7a mais cedo do que outros exames imagiol\u00f3gicos porque mostra altera\u00e7\u00f5es qu\u00edmicas a n\u00edvel celular, fornecendo informa\u00e7\u00f5es sobre:<\/span><\/p>\n

    \n
  • A presen\u00e7a de doen\u00e7a<\/span><\/li>\n
  • A localiza\u00e7\u00e3o e a extens\u00e3o da doen\u00e7a<\/span><\/li>\n
  • A rapidez com que a doen\u00e7a se est\u00e1 a propagar<\/span><\/li>\n
  • Se o tratamento est\u00e1 a funcionar<\/span><\/li>\n<\/ul>\n

    O que esperar de um exame PET\/CT<\/b><\/h2>\n

    O exame PET ser\u00e1 efectuado num dos nossos <\/span>hospitais<\/span> ou um <\/span>centro de imagiologia<\/span> que lhe seja conveniente. Depois de vestir uma bata, receber\u00e1 o marcador atrav\u00e9s de uma inje\u00e7\u00e3o numa veia. Pode demorar at\u00e9 uma hora para o seu corpo absorver o marcador. <\/span><\/p>\n

    O aparelho de PET\/CT tem o aspeto de um t\u00fanel ou de um grande donut de lado. O doente deita-se numa mesa que desliza para dentro do aparelho e tem de permanecer im\u00f3vel durante o exame, enquanto o aparelho capta os sinais do marcador para produzir imagens. O exame em si \u00e9 indolor. O tempo que demora varia, mas pode durar at\u00e9 uma hora. <\/span><\/p>\n

    O que significam os resultados da PET\/CT<\/b><\/h2>\n

    O marcador acumula-se em \u00e1reas do corpo com elevada atividade qu\u00edmica. Isto aparece como pontos brilhantes na PET. Estas s\u00e3o \u00e1reas que podem indicar doen\u00e7a. <\/span><\/p>\n

    Um radiologista <\/span>Um m\u00e9dico com forma\u00e7\u00e3o espec\u00edfica em interpreta\u00e7\u00e3o de PET scan examinar\u00e1 as imagens e comunicar\u00e1 os resultados ao seu m\u00e9dico. Resultados normais significam que o tra\u00e7ador n\u00e3o se acumulou de forma anormal em nenhum local. Resultados anormais podem revelar a presen\u00e7a ou a dissemina\u00e7\u00e3o de cancro.<\/span><\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
