Asphericity of pretherapeutic tumour FDG uptake provides independent prognostic value in head-and-neck cancer

Objective To propose a novel measure, namely the ‘asphericity’ (ASP), of spatial irregularity of FDG uptake in the primary tumour as a prognostic marker in head-and-neck cancer. Methods PET/CT was performed in 52 patients (first presentation, n  = 36; recurrence, n  = 16). The primary tumour was seg...
