On these maximal intensity projections of 68Ga-DOTATATE PET, there are 8 different clinical scenarios of stage IV gastrointestinal NET. Despite the similar disease stage, all these patients deserve personalized management of their disease according to several patient- and tumor-specific factors. For optimal management, choice of treatment should be discussed in an experienced multidisciplinary setting.
