Endovascular catheter-based procedures under MRI can be challenging as standard fabrication methods for markers are rigid and bulky, and new microfabrication methods need more analysis on their tracking characteristics. We analyzed a wireless resonant circuit tracking marker that was printed using aerosol jet deposition on a polymer catheter. In a phantom, we acquired bSSFP sequences and a B1+ map, and measured temperature using probes and MR thermometry. In vivo, in the carotid arteries, we acquired GRE sequences and a B1+ map. The marker demonstrated good signal, with minimal temperature increases, suggesting that these markers have good tracking characteristics.
