Implantable infusion pumps are internally powered devices surgically placed subcutaneously in the upper chest or abdominal wall. They consist of a titanium-encased pump assembly (containing a drug reservoir and refilling port) connected to a small-gauge plastic catheter.

For MRI safety and diagnostic information related to all inactive models, refer to the Model 8626 and 8627 SynchroMed EL pumps and the Models 8615, 8616, 8617, and 8618 SynchroMed pumps section on page 16.

Only implantable infusion pumps labeled MR Conditional may be safely scanned, and only under the specified conditions of safe use. Contact the implantable infusion pump manufacturer if there are any questions about the MRI safety status of the implantable pump system.

Many of these pumps contain ferromagnetic materials and could even become projectiles in the MR environment. All insulin pumps are therefore considered MR Unsafe and must be removed prior to entry into the MR scanner room.

Nearly all other non-port vascular access catheters and devices do not contain metal and are MR Safe. These include Peripherally Inserted Central Catheter (PICC) lines, central venous catheters (CVCs), and tunneled catheters (e.g., Hickman, Broviac, Permacath, Leonard, and Groshong).

Active implants contain their own power source, so a), an implanted infusion pump is the only correct answer since it has a battery. Magnetic dentures and programmable CSF valves contain permanent magnets, but do not have an intrinsic power source.

Aug 21, 2008 · Non-clinical testing has demonstrated that all Arrow® Intra-aortic Balloon Pumps (IABP) are MR Unsafe. There are no MRI scanning conditions that can be performed safely in the presence of the IABP system. If the physician determines that an MRI is necessary, IABP pumping must be stopped and all cables, such as the ECG cable, AP

MRI may affect implants through a wide range of mechanisms as categorized in the table below. All risks associated with passive implants (displacement, rotation, heating, and magnetization) apply to active implants as well, but active implants have additional risks.

Are respiratory stimulation systems for diaphragmatic paralysis and sleep apnea safe for MRI?
