PURPOSE: To provide information on ferromagnetic metallic implants, materials, and
devices that may be exposed to static magnetic fields during magnetic resonance (MR) …

The objective of our investigation was to evaluate safety during MR imaging (ie, magnetic
field interactions, heating, and artifacts) for metallic stents. Different types of metallic stents …

Abstract The MR Section of The National Electrical Manufacturers Association (NEMA), in
response to a request from the Food & Drug Administration (FDA), recently issued a position …

Magnetic resonance (MR) imaging is contraindicated for patients with certain ferromagnetic
implants, primarily because of potential risks related to movement or dislodgment of the …

With cochlear implants, magnetic resonance imaging (MRI) has until recently been
contraindicated due to excessive magnetic and electromagnetic interference. The aim of this …

This study compares artifact from craniomaxillofacial internal fixation devices in magnetic
resonance images and examines heating and magnetic deflection effects on these devices …

The purpose of this study was to evaluate the MR safety of cardiovascular catheters and
accessories. Intravascular cardiovascular catheters and accessories were tested for MR …

Ex vivo testing techniques were used to determine the ferromagnetic qualities of, presence
of heating in, and artifacts produced by 13 different heart valve prostheses exposed to a 1.5 …

Purpose To determine the MR compatibility of common dental retainer wires at 7 Tesla in
terms of potential RF heating and magnetic susceptibility effects. Methods Electromagnetic …

In vitro experiments were performed to determine the compatibility of a cochlear implant at
0.2-and 1.5-T magnetic resonance (MR) imaging. Except for the torque at 1.5 T, all …
