STENT AND MR IMAGING METHOD FOR REPRESENTING AND DETERMININGTHE POSITION OF A STENT

摘要

The invention relates to a magnetic resonance imaging process for representing and determining the position of a stent inserted in an examination object, and to a stent. In accordance with the invention, the stent (1) has at least one passive oscillating circuit (4) with an inductor (2) and a capacitor (3). The resonance frequency of this circuit substantially corresponds to the resonance frequency of the injected high-frequency radiation from the MR system. In this way, in a locally limited area situated inside or around the stent, a modified signal answer is generated which is represented with spatial resolution.
