It is commonly undesirable to see an RF coil in MR images. Novel research into innovative coil designs often involves the use of new materials that can be visible in MR images. In this abstract, we address this limitation by doping the coil substrate with Magnevist, drawing from a little-known phenomenon of signal hypointensity via T2-shortening for large concentrations of gadolinium-based (Gd) contrast agents that is especially applicable to hydrogen-rich materials. We show successful reduction of MR signal of >60% using our previously developed stretchable, liquid-metal based Ecoflex coil (6) using relaxometry measurements and in vitro experiments.
