Is there a role for FDG-PET?

In the last few years, imaging techniques such as FDG-PET have come to play an important role in the daily clinical practice for diagnosis, staging and follow-up of patients. Due to a lack of generally accepted standard guidelines, results from different clinical trials are difficult to compare and the role of PET-CT in a set of standard response criteria remains unclear. Therefore, a new warehouse is being constructed with collection for each patient of parallel CT and FDG-PET measurements. The source of heterogeneity of FDG-PET and its added value to the current RECIST will be evaluated.
