Conclusion La espectroscopia con RM es una tecnica segura, que no aumenta morbilidad a nuestros pacientes, y de gran utilidad en el diagnostico de lesiones tumorales, asi como de lesiones no-neoplasicas, nos puede permitir diagnostico diferenciales de recurrencia tumoral vs radionecrosis, y nos permite seleccionar blancos seguros para la obtencion de muestra bajo tecnicas estereotaxicas.
