Spectro glio trial
• robust and reproducible technique for MR spectroscopy coregistration with planning CT. • Dosimetric comparaison on 16 patients : • IMRT SIB technique 72 Gy compared with 3D conformal RT 60 Gy :
– better target coverage, – better index conformity – better conformation number – equivalent or better OARs sparing .
