Radioterapia Veterinária, Braquiterapia, Radiação BetaResumen
La terapia beta es una forma de braquiterapia en la que la fuente emisora de rayos beta se coloca directamente en el área en la que se desea tratar. Las principales aplicaciones son en dermatología y oftalmología en el tratamiento de lesiones superficiales, porque las partículas beta tienen un gran poder de ionización y un alcance pequeño en el tejido. La radioterapia en medicina veterinaria ha ido aumentando y presentando resultados considerablemente en Brasil y en todo el mundo. Esta revisión tuvo como objetivo describir los principios y aplicaciones de la terapia beta en medicina veterinaria. Para la realización, se realizó una investigación bibliográfica que permitió consolidar información relacionada con la base teórica y el tema propuesto. El uso de Estroncio-90 (Sr90) se observó en los principales procedimientos realizados en animales domésticos, salvajes y experimentales, destacando la importancia de esta técnica adyuvante. Se ha demostrado que la terapia beta es factible y fácil de manejar para aplicaciones veterinarias, especialmente en casos de lesiones superficiales y neoplasias. Las fuentes radiactivas emisoras beta, como las de Sr90, no requieren un gran cuidado con la protección radiológica, lo que contribuye a la viabilidad de su manipulación en radioterapia veterinaria, especialmente en procedimientos intraoperatorios.
