Abstract
A medicina nuclear utiliza substâncias radioativas para diagnosticar e tratar doenças. Essa especialidade médica, capaz de fornecer informações fisiológicas e metabólicas sobre o corpo humano, se tornou uma ferramenta fundamental para a detecção precoce de muitas desordens, inclusive vários tipos de câncer. O presente artigo descreve os marcos históricos da medicina nuclear, os princípios físicos básicos que subjazem à tomografia por emissão de pósitrons (PET), um método de imagem usado para mapear a distribuição de radiofármacos no corpo para fins diagnósticos e terapêuticos, e o estado atual dessa modalidade no Brasil.(AU)
 
In nuclear medicine, radioactive substances are used to diagnose and treat disease. This medical specialty, that can provide information about the human body's physiologic and metabolic processes, has become a key diagnostic tool for the early detection of many different disorders, including various types of cancer. The present article describes the historical milestones in nuclear medicine; the basic physical principles underlying positron emission tomography (PET), which is an imaging method used to map the distribution of radiopharmaceuticals in the body for diagnostic and therapeutic purposes, and the current status of this modality in Brazil.(AU)
