What is a consequence of improper screening of MRI patients?

The consequence of improper screening of MRI patients leads to an increased risk of adverse events. MRI is a powerful imaging modality that utilizes strong magnetic fields and radiofrequency waves, which can pose safety risks to certain patients. When proper screening protocols are not followed, patients with contraindications—such as those with implanted medical devices (like pacemakers or certain types of stents), ferromagnetic foreign bodies (like shrapnel), or certain tattoos that contain metallic inks—may be placed in the magnet's environment. These patients are at risk for serious complications, including device malfunction, burns, or even physical harm due to the strong magnetic attraction.

Screening for MRI compatibility is vital to ensure patient safety and to minimize potential hazards during the scanning process. This includes conducting thorough histories and interviews assessing past medical interventions, conducting metallic safety questionnaires, and implementing specific protocols to identify at-risk patients. When these steps are not adhered to, the likelihood of experiencing harmful adverse events escalates significantly.
