Additionally, patients will receive mpMRI just before and IV-contrast enhanced CBCT during their second and last fraction of RT, in addition to the standard of care CBCT that is acquired for daily image-guided patient positioning. Patients will undergo both IV-contrast enhanced CBCT and treatment on the TrueBeam with HyperSight imaging capability.
