A promising clinicalimaging strategy to visualize (benign) insulinomas and native betacells in the pancreas is based on glucagon-like peptide-1 receptor(GLP-1R) targeting using radiolabeled exendin and SPECT/CT or PET/CT.3−5 The GLP-1R is highly and specifically expressed on beta cells. Here, GLP1R is linked to pancreatic insulinoma.
