ROBILOTTA, Cecil Chow. Positron emission tomography: a new modality in Brazilian nuclear medicine. Rev Panam Salud Publica [online]. 2006, vol.20, n.2-3, pp.134-142. ISSN 1680-5348. http://dx.doi.org/10.1590/S1020-49892006000800010.
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.
Keywords : radiopharmaceuticals; diagnostic imaging; PET; functional image; Brazil.
