Neuroendocrine tumours (NETs) are a group of neoplasms generally arising from the
gastroenteropancreatic tract. They are usually slow growing, have low malignant potential,
and often go unnoticed until they become metastatic. The correct treatment approach is
dependent on the extent of the disease, however surgical approaches and systemic therapy can
be curative.
Combined positron emission tomography/computed tomography (PET/CT) using the radiotracer
18F-6-L-fluorodihydroxyphenylalanine (18F-FDOPA) has been shown to be a promising
non-invasive technique to help localizing NETs and guide their treatment.
