There are an increasing number of medical devices which patients can present with. The MRI community tend to call these devices Active Implanted Medical Devices (AIMD’s). These are typically implanted devices that have active electronic or magnetic components. That is, they are distinct from passive implant devices or devices with purely mechanical features.
What is included here is a list of common AIMD’s and guidance as to how a patient with these devices may be safely scanned in MRI.
Implantable Loop Recorders (ILRs) – including Medtronic Reveal and Reveal Linq devices
Glucose Monitors – including Abbot Freestyle Libre
Sacral Nerve Stimulators, SNS (e.g. Medtronic Interstim)
Pill Cam (Capsule cameras for endoscopy)
Deep Brain Stimulators, DBS
Vagal Nerve Stimulator, VNS (e.g. Livanova (formerly Cyberonics))
Enterra / Enterra 2
LINX device
ICP monitor guidance
