Abstract

LOS METODOS ANTERIORES PARA LA CUANTIFICACION DE MOLECULAS ETIQUETADAS RADIOSCOPICAMENTE QUE EMPLEAN ISOTOPOS QUE EMITEN UN SOLO ELECTRON, POSITRON O GAMA-FOTON. SU SENSIBILIDAD ESTA LIMITADA POR LOS SUCESOS DE FONDO QUE NO PUEDEN DISTINGUIRSE DE LA DESINTEGRACION DE LA ETIQUETA ISOTOPICA. EXISTEN ISOTOPOS QUE SE DESINTEGRAN CON LA PRODUCCION CONCURRENTE DE UN POSITRON Y DE UN GAMA-FOTON, CON UNA POSTERIOR ANHILACION POSITRON-ELECTRON QUE PRODUCE PARES DE GAMAS 511 KEV CON MOMENTOS OPUESTOS. EL DETECTOR COINCIDENTE GAMA-FOTON REGISTRA UNA CUENTA CUANDO SON DETECTADOS GAMA-FOTONES COINCIDENTES DE ENERGIAS CONOCIDAS. CUANDO SE SINTONIZA LA FIRMA DE LA TRIPLE GAMA DE UN ISOTOPO PARTICULAR, EL CGD CONSIGUE UN RECHAZO EXCEPCIONAL DEL FONDO, CON EL RESULTADO DE CAPACIDADES MEJORADAS PARA CUANTIFICAR PEQUEÑAS TRAZAS DEL ISOTOPO. CON LA SENSIBILIDAD INCREMENTADA ASI CONSEGUIDA, EXISTEN NUEVAS UTILIZACIONES DE LOS GAMAS MULTIPLES PRODUCTORES DE ISOTOPOS, Y EN LA CUANTIFICACION DE MOLECULAS EN QUE PUEDEN SER INCORPORADAS.
