Tomografía por Emisión de Positrones: Los nuevos paradigmas
Positron Emission Tomography: new paradigms
1Unidad PET-Ciclotrón, Facultad de Medicina, UNAM. Ciudad Universitaria, Av. Universidad # 3000, Coyoacán 04510, México, D.F.
La tomografia por emisión de positrones (PET) es una sofisticada técnica empleada en medicina nuclear para el diagnostico no invasivo de distintas enfermedades. En el PET están fusionadas varias tecnologías para la generación de información cuantitativa, espacial y funcional de los procesos biológicos a través de la obtención de imágenes de los eventos moleculares y celulares tomadas directamente de los organismos vivos, empleando radiofármacos PET.
Palabras Clave: Ciclotrón; imagen molecular; PET; radiofármaco PET; tomografia por emisión de positrones
Positron Emission Tomography (PET) is a sophisticated technique used in nuclear medicine for non-invasive diagnostic of several diseases. Several technologies that generate quantitative, spatial and functional information about biological processes are fused in PET. Such information is obtained through images of molecular and cellular events which are directly taken from living organisms by using radiochemicals PET.
Key Words: Cyclotron; molecular imaging; PET; radiopharmaceutical PET; positron emission tomography
