摘要: ABSTRACT Head and neck cancer is considered a public health problem worldwide, given its high morbidity mortality. The more advanced the histopathologic grade, aggressive may be therapies. development of policies, diagnosis treatments lead to better prognostic perspectives. This paper aimed review literature regarding application positron emission tomography in head cancer, including impact diagnosis, image principles, radiotracers, / computed fusion other advantages. was performed following systematized search strategies reported literature. It could observed that use improves diagnostic approach patients, especially when allied tomography. As it provides physiological information, also benefits reduces related treatment cancer. Indexing terms: Carcinoma, squamous cell. Head cancer. Positron-emission tomography. RESUMO Apresentando-se como um problema de saude publica em todo o mundo, câncer cabeca e pescoco caracteriza-se por sua alta morbidade mortalidade. Quanto mais avancado grau diferenciacao tumoral, mutiladoras tendem ser as terapias empregadas. Desta forma, os avancos nos âmbitos da promocao saude, diagnostico tratamento sao extremamente beneficos ao prognostico. Esta revista literatura tem objetivo discorrer sobre aplicacao tomografia emissao positrons no planejamento terapeutico pacientes portadores tumores malignos pescoco, principios formacao imagem, radiofarmacos utilizados, fusao imagens computadorizada suas contribuicoes. O levantamento bibliografico foi efetuado segundo estrategias sistematizadas relatadas literatura. Fornecendo informacoes relativas fisiologia das lesoes atraves administracao radiofarmacos, pode observado que positrons, especialmente quando aliada computadorizada, maximiza possibilidades diagnosticas determinadas indicacoes, favorecendo prognostico sugerindo reducao na decorrente do pescoco. Termos Indexacao: Carcinoma celulas escamosas. Neoplasias pescoco. Tomografia positrons.
