Positron emission tomography with fluorine-18 fluorodeoxyglucose (FDG-PET) is currently used in the re-staging of colorectal cancer after surgery, particularly when an increased plasma levels of markers are observed or when a pelvic mass is suspected to be a local recurrence rather than an effect of the radiation treatment FDG-PET may be also used for staging and re-staging of many other gastrointestinal tumours, although the global accuracy may be lower than that observed in colo-rectal cancer, particularly in hepatocellular carcinoma. However, this imaging technique may play a more than ancillary role in the differential diagnosis of hepatic or pancreatic nodules, because of ability to detect further sites of FDG uptake (metastases) or into assessing a different prognosis for patients with tumours and different levels of differentiation.
