Multimodal exendin for theranostics of insulinoma. Radiolabeled exendin‐4 can be used for SPECT or PET imaging to locate the lesion (1), however to detect the lesion intraoperatively a gamma probe (2) and fluorescence imaging (3) can be used. Furthermore the lesion can then be treated with NIR light to eradicate GLP‐1R expressing cells (4).
