The EmeryGlide (TM) guidewire is an MRI conditional guide wire which is safe to use in 1.5 and 3.0 Tesla for real-time interventions according to ASTM F2182, F2052, F2053 and F2213 standards. The wire has discrete MRI markers and the entire wire is radiopaque (ASTM F640-79). In addition its construction with a double internal winding and the entire body and tip are packed into one sleeve to prevent detachment of tip and breaking of the internal core. The MRWire has CE 0344, FDA 510 K approval and is registered by Health Canada

Video below: MR image (1.5 tesla, GRE) showing discrete markers in the tip and distal from the tip create MRI image artefacts tested by ASTM F2119. The image above shows the artifacts evenly distributed over a guide wire inserted in the right renal artery, followed by ballon dilatation, pull-back of catheter and stenting (large artifact).
