Gradient induced implant heating
While heating of metallic passive implants (e.g., hip replacement implants) due to switched gradient fields in MRI can, in some cases, exceed radiofrequency (RF) induced heating, and pose an often-unrecognised hazard for implant carriers, this is not reflected in documentary standards. Some normative documents, e. g. ASTM F2182 ignore this effect completely, while others e.g., ISO/TS 10974 are limited in scope just to those implant categories where that effect is least relevant.
