Neuroendocrine Tumors
Conditions
Brief summary
This is an open-label, single-dose, single-arm, single-center imaging study using DOTATATE peptide, labelled with the 64Cu tracer.
Detailed description
In total, 59 subjects will be recruited in the study. The study will recruit both healthy volunteers as well as patients with confirmed or suspicious NET disease by histology or conventional anatomical and functional imaging modalities including but not limited to magnetic resonance imaging (MRI), and/or computed tomography (CT), and/or, F-18 FDG fluorodeoxyglucose PET (positron emission tomography)/CT and /or F-18 NaF sodium fluoride bone PET/CT and/or bone scintigraphy, and/or Octreoscan.

Eligibility
Inclusion criteria
* Confirmed or suspicion of NET based on histology/ biopsy report. * Confirmed or suspicion of NET based on conventional imaging scans of affected area such as MRI and/or contrast enhanced CT and/or an FDG PET * CT scan and/or NaF PET-CT scan and/or OctreoScan® performed within 8 weeks prior to study date.
Exclusion criteria
* Pregnant, planning to be pregnant within the next two weeks * Inability to provide written consent. * Therapeutic use of any somatostatin analogue, including Sandostatin® long-acting and Lanreotide (within 28 days) and Sandostatin® (within 2 days) prior to study imaging. If a subject is on Sandostatin® long-acting or Lanreotide, a wash-out period of 28 days is required before the injection of the study drug.
