Right renal artery-dilatation and stenting in MRI
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 balloon dilatation, pull-back of catheter and stenting (large artefact).
