Overview

MRI may be helpful in the diagnosis of multiple endocrine neoplasia type 1.

MRI

Gastrointestinal Neuroendocrine Tumors

  • MRI findings of gastrointestinal neuroendocrine tumors include the following:[1]

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
