Overview
MRI may be helpful in the diagnosis of multiple endocrine neoplasia type 1.
MRI
Gastrointestinal Neuroendocrine Tumors
- MRI for gastrointestinal neuroendocrine tumors:[1]
- MRI is used for suspected hepatic, pancreatic or retroperitoneal neuroendocrine tumors, often with gadolinium contrast.
- MRI enterography is also possible
Insulinoma
- MRI findings of insulinoma include the following:[2]
Somatostatinoma
- MRI findings of insulinoma include the following:[4]
- Smaller lesions may be difficult to diagnose.
- Signal characteristics of larger lesion include:
- T1: low signal 1,8
- T2: high signal 1,8
- T1 (C+) Gd: most show early diffuse heterogenous enhancement
