Overview
MRI may be helpful in the diagnosis of multiple endocrine neoplasia type 1.
MRI
Gastrointestinal Neuroendocrine Tumors[1]
- Used for suspected hepatic, pancreatic or retroperitoneal NETS, often with gadolinium contrast.
- MRI enterography also possible.
Insulinoma[2]
- Dynamic MRI with fast gradient echo sequences following bolus injection of contrast medium may aid the detection of these tumours[3]
- T1 C+ (Gd): typically shows enhancement, although contrast enhancement may not improve tumour visualisation compared with non-contrast images
Somatostatinoma[4]
- Smaller lesions may be difficult to diagnose. Described 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
