An alternative like an aluminum bronze alloy works in an MRI space, too, but its also pricey: an adjustable wrench out of this material costs in the $200 to $300 range. The use of implantable pacemakers and implantable cardioverter-defibrillators (ICDs) has increased dramatically, due in part to expanded indications for their use and the aging of society. (Slightly dated, but an excellent and enduring explanation of susceptibility from a pioneer in MRI and first inductee in GE's Genius Hall of Fame). Conditional 2 These particular weakly ferromagnetic coils, filters, stents, clips, cardiac occluders, or other implants typically become firmly incorporated into the tissue six weeks following placement. Metal may interfere with the magnetic field used to create an MRI image and can cause a safety hazard. Before any patient steps into an MRI room, they are asked to remove any metal objects like purses, watches, belts, wallets, credit cards, etc. Definitions of MRI classification are generally taken from ASTM standard for "Standard Practice for Marking Medical Devices and Other Items for Safety in the Magnetic Resonance Environment", F2503.
