Overview

MRI is helpful in the localization of paraganglioma; MRI demonstrates a high signal mass.

MRI Findings in Paraganglioma

• Similar to CT scan, magnetic resonance imaging (MRI) imaging of the abdomen and pelvis (at least through the level of the aortic bifurcation) is a common methods for localization of paragangliomas.

• MRI has a similar sensitivity (90%–100%) and specificity (70%–80%) compared to CT scan; however, CT imaging provides superior anatomic detail compared with MRI.
