Overview
Over 10 million people worldwide have an implantable electronic device. Historically, MRI has been denied to patients with such devices due to early reports about severe complications. Recent studies suggest that MRI can be performed safely and effectively in these patients with proper screening and reasonable precautions, but the emerging evidence has not translated into appropriate access to MRI. Radiologists and clinicians continue to deny MRI in patients with implantable devices due to unsubstantiated fears of complications. In some instances, MRI is refused unless the device is explanted, exposing patients to unnecessary cost, delay, morbidity, and even mortality. This plenary session reviews the theoretical and historical basis for the concerns about MRI in patients with implantable devices, examines the current scientific evidence on the actual risks, and gives guidance on best practices for safe and effective MRI.

Target Audience
Radiologists, radiology residents and fellows, MR modality chiefs, MR technologists, radiology nurses, MR safety officers, MR physicists, clinicians who manage patients with implantable devices, medical/imaging center administrators, and scientists and other personnel from electronic implantable device manufacturers.

Educational Objectives
As a result of attending this course, participants should be able to:
- Identify standard terminology for implantable electronics devices;
- Summarize the scope of the problem: how many patients have implantable electronic devices worldwide and in different geographic regions, and how many patients are denied MRI exams unnecessarily;
- Paraphrase the history and current scientific evidence on the safety and risks of MRI in patients with implantable electronic devices;
- Explain the most common CV implanted devices, recommended safety precautions, recommended patient information, guidance for efficient and safe imaging of patients with implantable CV devices, and where to turn to for advice; and
- Discuss the most common non-CV implanted devices, recommended safety precautions, recommended patient information, guidance for efficient and safe imaging of patients with implantable non-CV devices, and where to turn to for advice.
