What is the primary risk of utilizing unapproved devices in MRI?

Utilizing unapproved devices in MRI poses a significant risk primarily due to the potential for patient injury. Devices that lack approval may not have undergone rigorous safety testing for use in the powerful magnetic fields and radiofrequency fields present in an MRI environment. As a result, these devices could behave unpredictably, leading to malfunction or physical harm. They might contain materials that are ferromagnetic, which can cause them to become projectiles, or they may not be compatible with the MRI system, leading to overheating or other hazardous situations.

While device malfunction and increased image artifacts could also occur, the foremost concern is the well-being and safety of the patient. Ensuring that all devices in use are approved and tested minimizes these risks, creating a safer environment for both patients and staff in the MRI suite.
