Fig. 5From: How we read: the combined use of MRI and novel PET tracers for the characterisation and treatment planning of masses in neuro-oncologyGaTate-PET (a) in a patient with metastatic NET identifies a lesion in the posterior fossa (arrowhead). Given the proximity to the tentorium cerebelli, both an incidental meningioma and a NET metastasis are in the differential. The mixed solid and cystic appearance on the post-contrast MRI (b) confirms a metastasis. MRI also demonstrates a smaller enhancing focus more inferiorly in the posterior fossa (c), consistent with a further NET metastasisBack to article page
