Overview
MRI may be helpful in the diagnosis of multiple endocrine neoplasia type 1. Findings on MRI suggestive of multiple endocrine neoplasia type 1 include diffuse heterogenous enhancement of T1 C+ (Gd), low T1 signal and high T2 signal.
MRI
Gastrointestinal Neuroendocrine Tumors
- MRI is used for suspected hepatic, pancreatic or retroperitoneal neuroendocrine tumors, often with gadolinium contrast.[1]
- MRI enterography is also possible
Insulinoma
- Dynamic MRI with fast gradient echo sequences following bolus injection of contrast medium may aid the detection of these tumors[2]
- MRI findings of insulinoma include the following:[3]
Somatostatinoma
- T1: low signal
- T2: high signal
- T1 (C+) Gd: most show early diffuse heterogenous enhancement
