Overview

Abdominal MRI is helpful in the diagnosis of glucagonoma. On abdominal MRI, glucagonoma is characterized by a mass which is hypo-intense on T1-weighted MRI and hyper-intense on T2-weighted MRI. MRI is preferred over contrast-enhanced CT or somatostatin receptor scintigraphy for assessing metastasis.

MRI

  • Findings on abdominal MRI suggestive of glucagonoma include:[1]
    • T1: low signal intensity
    • T2: high signal intensity
  • MRI is preferred over contrast-enhanced CT or somatostatin receptor scintigraphy for assessing metastasis.
