Abstract
The subject invention relates to a stent with respect to which the occurrence of artifacts in nuclear spin tomography can be reduced or avoided. The subject invention also pertains to the etching of stents, incorporating titanium and/or titanium alloys, that have been processed with tools containing magnetizing components. The subject invention can also be useful for the control of in-stent-restenosis by allowing imaging under nuclear spin tomography to see in-stent-restenosis in the interior of the subject stent.
