Aplicaciones del PET/CT en oncología

Juan P. Oliva González, Aldo Martínez Ramírez, Richard Paul Baum

Resumen

PET significa Tomografía por Emisión de Positrones y es una técnica de medicina nuclear en la cual se emplean radiofármacos marcados con emisores de positrones que permiten obtener imágenes bioquímico-metabólicas del cuerpo humano. El PET/CT permite obtener imágenes multimodales que combinan información anatómica y metabólica y permiten realizar un diagnóstico más seguro de un tumor o de las metástasis locales o a distancia en un órgano o tejido. Otros equipos multimodales combinan las imágenes metabólicas con la resonancia magnética nuclear. El PET/CT se emplea fundamentalmente en Oncología (85-90 %), Neurología, Cardiología, Inflamación e Infección, aunque actualmente también es empleado en diferentes patologías médicas y quirúrgicas. En el presente trabajo deseamos mostrar qué es el PET/CT y su utilidad en la Oncología.
