Magnetic resonance imaging (MRI) offers a superior combination of 3D imaging with high-resolution special and temporal resolution, low observer dependency, no radiation exposure, and none of the risks associated with iodinated contrast agents.

With dynamic contrast-enhanced MRI, dynamic changes in MR signal intensity in selected tissues can be detected. Some of the newer generation contrast agents can be loaded with specific antibodies that allow for targeted imaging.

MRI has a higher sensitivity for detecting pelvic masses than ultrasonography but is limited in identifying diffuse pelvic endometriosis.
