Positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) exploits the abnormal energy metabolism of tumours to enable functional as opposed to structural imaging. The last decade has seen more than 100 reports of the sensitivity and specificity of FDG-PET for the detection and staging of cancer in various settings [1]. These show that a combination of PET and conventional imaging mostly outperforms conventional imaging on its own, in its ability to predict histopathological reference findings. The progression of research in clinical PET to address combined modality therapies is welcome, and it is encouraging to see the results of groups represented by Flamen and colleagues published in dedicated oncological journals such as the Annals [2]. The increasing predictive power of diagnostic technologies is bound to change the way we practice medicine in coming years. In fact, the technologies themselves are already here; the real challenge is to identify
