Example of ¹⁶⁶Ho-radioembolization in NET. A patient with a grade 2 small intestinal NET according to the WHO-criteria, treated in the prior HEPAR 2 trial. On the left, the ¹⁸FDG-PET and venous phased CT at baseline. In the middle, the imaging studies 3 months after ¹⁶⁶Ho-RE with partial metabolic ¹⁸FDG-PET response and some tumour reduction on CT. On the right, follow-up imaging studies 6 months after ¹⁶⁶Ho-RE with significant partial metabolic response and significant tumour reduction on CT
