Abstract
The invention relates to a magnetic resonance imaging process for the imaging and determination of the position of a stent introduced into an examination object as well as to the stent so utilized. According to the invention, the stent has at least one passive resonance circuit with an inductance and a capacitance whereby its resonance frequency is essentially equal to the resonance frequency of the applied high-frequency radiation of the magnetic resonance system. A changed signal response is thus produced in a locally defined area in or around the stent which is imaged in spatial resolution.
