Brief Summary:

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.

Study Type : Expanded Access
Official Title: [18 F]-6-L-fluorodihydroxyphenylalanine (18F-FDOPA) Positron Emission Tomography (PET) in Neuroendocrine Tumours

Intervention Details:
  • Drug: [18 F]-6-L-fluorodihydroxyphenylalanine (18F-FDOPA)

    All patients will have their weight and baseline vital signs recorded.

    The study subject will have an intravenous catheter inserted and receive a slow bolus intravenous dose of 185 - 370 MBq (5 -10mCi) 18F-FDOPA.

    The patient will rest in a comfortable reclining chair in a warm, private shielded room for 45 to 60 minutes.

    Patients are positioned supine and centered on the scanner bed for an average total scan time (CT and PET) of approximately 30 minutes.

    Images will be interpreted by qualified and experienced physicians. Findings of significance from the PET/CT scan, and any incidental findings of significance from the CT scan, will be included in the single final report that will be issued to referring physicians.

    Other Name: 18F-FDOPA
