Insulinoma: Insulinoma are rare, small insulin secreting neuroendocrine tumors. The only curative approach is the surgical excision. The preoperative detection remains a challenge. A non-invasive, highly sensitive tool in localizing the insulinomas would be appreciated in the preoperative work-up of these patients. To this aim Glucagon-like peptide-1 receptor (GLP-1R) imaging (Single Photon Emission Computer Tomography co-registered with a CT; SPECT/CT) could be a convenient tool. The possibly more sensitive approach of targeting GLP-1R using Positron emission tomography (PET/CT) methodology has not been investigated in patients so far.
