Magnetic resonance imaging findings following button battery ingestion.

Background: Lithium button battery ingestions have been increasing in frequency since the early 2000s and can develop severe and sometimes fatal complications from caustic injury even after rapid battery removal. To aid in clinical decision-making, we began obtaining magnetic resonance imaging (MRI)/MR angiography in these patients.

Objective: Our goal was to review MRI/MR angiography imaging in button battery ingestion cases and compare with other imaging, clinical data and outcomes in these patients.
