Risks: Thermal, Displacement
- Implanted < 6 weeks: confirm that the device is FDA cleared and comply with conditions of FDA approval.
- Implanted > 6 weeks: MRI permissible.
- Urgency and benefit of the clinical indication may outweigh the theoretical risk of MRI. This should be assessed on a case by case basis and approved by a radiologist.
Bottom Line: MRI permissible if implanted > 6 weeks. If implanted < 6 weeks, all conditions must be met.
