Analysts queried the Pennsylvania Patient Safety Reporting System database for MRI screening events submitted from January 1, 2009, through December 31, 2017. Of the identified 1,108 MRI screening events, the reports range from uncompleted MRI screening forms to ferromagnetic projectile events causing patient injury. Additional factors evident from analysis included the following (see also Figure 1):
- Five events were designated as Serious Events:
- One was related to a nonmedical object projectile
- One led to a thermal injury from an external medical device
- Three led to malfunction or displacement of an internal medical device
- The number of reports has trended downward over the past 9 years.
- Of the MRI screening events with identifiable objects or devices, 64.8% (n = 708 of 1,093) involved internal medical devices and nonmedical objects; the most frequently involved items were pacemakers (32.3%, n = 353 of 1,093).
- More than one-third (35.2%; n = 385 of 1,093) of events involved external objects, carried in by or attached to the patient or healthcare staff.
