Value of MR contrast media in image-guided body interventions

Figure 2 Gadolinium-based magnetic resonance contrast media (T1 enhancing agent) have been used for multiple purposes in cardiac interventions. A:These agents (at a low concentration) have been used to create a target in the myocardium; B: Gadolinium oxide powder was used to coat the endovascular catheter to facilitate navigation into the LV (white arrowhead); C: Magnetic resonance (MR) contrast medium was also used for enhancing and measuring the target (myocardial infarct) (white arrows); D: Selected MR-guided images show an active catheter hitting the infarcted target.
