Tag: 18F-FDG PET/CT

Background It's normally the case that the higher the grade/Ki67 in Neuroendocrine Neoplasms (NENs), the less likely the tumours will have somatostatin receptors and therefore be able to take advantage of somatostatin receptor PET (SSTR PET) as the gold standard in nuclear imaging.  This is why most grade 3 NENs will receive [18F]FDG PET/CT which finds glycolytic activity in the tumour and predicts an aggressive disease course and normally a higher histological grade. It can also add to prognostic outcomes, which in turn can add to therapy choice decisions. There is an overlap though, particularly with the recognition of well-differentiated Grade 3 Neuroendocrine Tumours (NETs).  It is known that some glycolytic activity might be present in some well-differentiated NETs, in particular, grade 3 and the upper range of 2 Neuroendocrine…
