Radionuclide Imaging of Gastrointestinal Neuroendocrine Tumors

Abstract

Neuroendocrine tumors (NETs) are rare and heterogeneous epithelial neoplasms with neuroendocrine differentiation commonly originating from the gastrointestinal tract. In the evaluation of patients with suspected or known NETs, a multidisciplinary strategy including both radiological studies and nuclear medicine examinations is usually proposed to provide optimal therapeutic management. This chapter will focus on medical imaging for gastrointestinal NETs with emphasis on nuclear medicine techniques, taking into account the patient clinical context and both strengths and limitations of each diagnostic modality.
