To the Editor: As the use of magnetic resonance imaging increases, the number of hazards associated with the magnetic field also increases. These hazards range from the erasure of magnetic bank cards (1) to the creation of projectiles from ferromagnetic objects (2,3). The potential hazards are described in most textbooks (4) on magnetic resonance, clinicians are commonly given lists of contraindications to magnetic resonance studies, and technologists and radiologists are alert to the presence of ferromagnetic objects near the scanner. Uncommon ferromagnetic objects, however, may be unrecognized and enter the magnetic field. We report our experience with such an unrecognized
