Estudo do efeito do uso de colimador na sonda gama utilizada em cirurgia radioguiada

Abstract: OBJETIVO: O objetivo deste trabalho consiste em estudar a influência da resolução espacial da sonda gama Europrobe que é utilizada em cirurgia radioguiada. MATERIAIS E MÉTODOS: Na técnica de cirurgia radioguiada, após a injeção de um radiotraçador no tumor primário, é utilizada uma sonda detectora de radiação gama a fim de determinar a localização do linfonodo sentinela. Para simular a região dos pontos de injeção do radiotraçador e o linfonodo sentinela, duas fontes de Tc-99m, com 20,42 MBq e 0,70 MBq, foram … Show more

“…Today, there are several pieces of equipment commercially available to carry out the intraoperatory gamma detection such as Neoprobe ® , Europrobe ® , Navigator ® . However, most pieces of equipment are imported and expensive, which a lot of times limits their use to large centers 31,32 . They basically have a probe with a crystal or small gamma camera in one end, which is connected to a portable counter.…”
