12. Donotpositionelectricallyconductivematerialsacrossanexternalmetallicprosthesis

(e.g.,externalfixationdevice,cervicalfixationdevice,etcetera)orsimilardevicethatisin

directcontactwiththepatient.

13. Al lowonlyproperlytrainedindividualstooperatedevices(e.g.,monitoring

equipment)in

theMRenvironment.

14. Followallmanufacturerinstructionsfortheproperoperationandmaintenanceof

physiologicmonitoringorothersimilarelectronicequipmentintendedforuseduringMR

procedures.

15. ElectricaldevicesthatdonotappeartobeoperatingproperlyduringtheMRprocedure

shouldberemovedfromthepatientimmediately.

16. Closely

monitorthepatientduringtheMRprocedure.Ifthepatientreportssensationsof

heatingorotherunusualsens ation,discontinuetheMRprocedureimmediatelyand

performathoroughassessmentofthesituation.

17. RFsurfacecoil decouplingfailurescancauselocalizedRFpowerdepositionlevelstoreach

excessivelevels.TheMRsystemoperator

willrecognizesuchafailureasasetofconcentric

semicirclesinthetissueontheassociatedMRimageorasanunusualamountofimage

non‐uniformityrelatedtothepositionoftheRFcoil.

Theadoptionoftheseguidelineswillhelptoensurethatpatientsafetyismaintained,especially

asmoreconductivematerialsandelectronically‐activateddevicesareusedinassociationwith

MRprocedures.
