Limitaciones tecnológicas de la tomografía por emisión de positrones (PET) para pequeños animales de laboratorio

Abstract

La visualización y cuantificación de la función de determinados órganos en animales de laboratorio mediante PET está demostrando ser una herramienta de gran relevancia para la caracterización del fenotipo de animales transgénicos y noqueados, en el estudio de modelos de enfermedades humanas, así como para el descubrimiento y desarrollo de nuevos medicamentos y sondas bioquímicas. Para poder utilizar la PET en animales de laboratorio de un modo análogo al que se aplica en humanos es necesario contemplar el factor de escala en el tamaño del vóxel así como mantener una similar estadística de contaje. En este trabajo se apuntan los problemas que estos requerimientos representan tanto para el diseño técnico de los tomógrafos como para la realización de los experimentos, y desde esta perspectiva se analizan las soluciones tecnológicas más relevantes. Finalmente, se comentan brevemente algunas características de sistemas disponibles hoy comercialmente (microPET y FOCUS, HiDAC, eXplore VISTA, MOSAIC, YAP-(S)PET y rPET)
