This article discusses the patient safety incidents that can occur when ferromagnetic objects and devices have not been detected during MRI screening and reach the magnetic resonance (MR) scanner field possibly injuring the patient, staff or the MR scanner. 1,108 screening events were identified in the period of 2009 through 2017 through the Pennsylvania Patient Safety Reporting System. 83 events involved two or more objects and/or devices. Of the MRI screening events with identifiable objects or devices, 64.8% involved internal medical devices and nonmedical objects; the most frequently involved items were pacemakers (32.3%). More than one-quarter of the events involved a device or object brought into the MR scanner room that was not considered safe for MRI. Of the events involving projectiles, 10 of the 51 projectiles (19.6%) struck either a patient or a healthcare provider. This article provides strategies for keeping ferromagnetic objects and devices from reaching the MR’s scanner’s magnetic field and address screening protocol, patient education, personnel MR training, equipment MR labelling, environmental restrictions, and the appointment of an MR safety officer.
