  • NOTE: MRI compatible knee replacements, hip replacements, stents, etc. may be included as long as the labeling of these devices allow MRI scans conducted per this protocol
  • NOTE: MRI compatible mechanical, prosthetic, and bioprosthetic heart valves may be included as long as the labeling of these devices allow for MRI scans conducted per this protocol
  • NOTE: Non-removable dental implants may be included
  • Have a lead extender, adaptor, or capped/abandoned lead
