Abstract
The invention relates to a metallic endoprosthesis, which causes no significant artefacts on images taken by magnetic resonance tomography (MRT), as a result of the combination of the production materials with a special design, which permits an evaluation of the externally adjacent region and the lumen of the endoprosthesis by means of MRT. The endoprosthesis is made from a material with a magnetisability similar to human tissue. The design of the endoprosthesis is such that the members or wires of the endoprosthesis run extensively along the longitudinal axis of the endoprosthesis, without forming a closed circuit in a plane which is essentially perpendicular to the endoprosthesis longitudinal axis. Further variations of the endoprosthesis design are possible, which all offer a full compatibility with MR for the endoprosthesis.
