Dr Yuranga Weerakkody et al.
An Octreoscan is a scinitigraphic study that uses a 111In labelled octreotide which is a somatostatin analog. It is particularly useful for assessment of neuroendocrine tumours.
Examples include
- carcinoid tumour
- paraganglioma(s)
- small cell lung cancer
- pituitary adenoma
- neuroblastoma
- medullary thyroid carcinoma
- islet cell tumour of pancreas
Certain non neuroendocrine tumours can also show uptake in an octreoscan
Examples include
In addition certain autoimmune or granulomatous disease may also occasionally show uptake with octreotide
