Interim CT shrinkage and FDG-PET uptake predicted head and neck outcomes
Low CT tumour shrinkage strongly predicted poorer locoregional control, while high interim FDG-PET uptake predicted both poorer control and survival.

An MTV threshold of 50 mL identified patients with poorer survival who appeared to benefit from combined-modality treatment.
Radioactive carbon-11 beams enabled PET-guided range adjustment during irradiation, with biological outcomes matching insufficient, optimal and excessive beam penetration.
