Corresponding post-contrast MRI (left) and GaTate-PET (right) images of two cerebral metastases in a patient with metastatic NET. The medial right occipital metastasis (a; arrow) demonstrates high GaTate uptake (b). If this were a solitary metastasis, a response to PRRT would be expected. The medial right pre-central gyrus metastasis (c; arrowhead), however, demonstrates low GaTate uptake (d), and is unlikely to respond to PRRT
