Patent abstract
A method to detect the location of a catheter relative to a targeted location in a blood vessel is provided. One example method includes acquiring and displaying magnetic resonance (MR) images while a first MR contrast agent is present and while the operation of that first MR contrast agent is counter-acted by a second MR contrast agent. Both MR contrast agents may be introduced into a blood vessel by the catheter whose position is to be detected.
