Overview
There are no other imaging findings associated with [disease name].
OR
[Imaging modality] may be helpful in the diagnosis of [disease name]. Findings on an [imaging modality] suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
Other Imaging Findings
Positron Emission Tomography
Somatostatin receptor scintigraphy
- Somatostatin receptor scintigraphy(SRS) may be helpful in the diagnosis of pancreatic neuroendocrine tumors including insulinomas. As many insulinomas does not express somatostatin subtype 2 receptors, it is less sensitive(50-60%).[1][2] [3][4][5]
Findings on an SRS suggestive of/diagnostic of insulinoma include:
- Increased uptake of pentetereotride(synthetic somatostatin analogue)
- Increased uptake in sites of metastasis, commonly in hepatic involvement
