Which of the following statements is true regarding patients with implanted devices in an MRI?

Confirmation of device compatibility before MRI is a crucial step in ensuring patient safety. Many implanted devices, such as pacemakers, cochlear implants, or spinal stimulators, can be affected by the strong magnetic fields and radiofrequency energy produced during an MRI scan. Each device has specific guidelines regarding MRI safety, which may include restrictions or precautions, depending on its design and materials.

By verifying device compatibility with manufacturers' guidelines or medical device registries prior to an MRI, healthcare professionals can identify whether it is safe for a patient to undergo the procedure, what precautions are necessary, and if any alternative imaging methods might be advisable. This approach helps prevent adverse events that can occur if incompatible devices enter the magnetic field, ensuring that patients are protected while receiving necessary imaging.

The other statements lack necessary nuance regarding the safety of patients with implanted devices in the MRI environment. For example, it's important to note that not all patients with implanted devices can undergo MRI without restrictions, and non-ferrous devices might still have limitations in certain MRI settings. Additionally, simply stating that patients with any device can safely enter zone 4 overlooks the critical need for assessment before entering controlled areas in an MRI suite.
