Overview
Abdominal MRI is helpful in the diagnosis of VIPoma. On abdominal MRI, VIPoma is characterized by a mass which is hypointense on T1-weighted MRI and hyperintense on T2-weighted MRI.
MRI
- Findings on abdominal MRI suggestive of VIPoma include:[1][2]
- MRI with gadolinium enhancement is more sensitive compared to CT scan in diagnosis of liver metastases which are shown as peripheral ring enhancement.
