Radiothérapie interne vectorisée:211At : appropriate for a-therapy due to its half-life (7.2 hours).

Nucl Med Mol Imaging

2008; 35: 1709-24

Principaux avantages de TEP/SPECT

1- Durée d’examen plus court (2 à 5 hrs vs 45 min)

2- Spécificité supérieure (femmes et surpoids) (artéfacts d’atténuation non uniforme de SPECT)

3- Quantification possible (atteinte tri-tronculaire)

4- Dose patient 2 à 3 fois plus faible

Mise en place d’une « dual Target » permettant l’irradiation simultanée de

ConclusionsARRONAX est maintenant opérationnel

La production de strontium a débuté (sept/oct 2010)

Production de Cuivre-64 est prévue fin 2010

Production d’Astate-211 est prévue avril 2011

Plusieurs projets collaboratifs ont débuté :

– Theranean: activation of nanoparticle for brachytherapy

– Alpha-RIT: alpha immunotherapy using 211At

– Cu-ATSM pour l’hypoxie
