  Topological edge states in electromagnetic systems feature a set of
attracting fundamental properties and unveil prospective applications based on
disorder robustness and tailored localization. Despite active efforts in
implementing topologically-protected waveguides in 2D photonic systems,
applications of 1D topological systems remain almost uncharted. This letter
demonstrates that topological edge modes can be realized in
metamaterial-inspired volumetric resonators with a practical application in
clinical magnetic resonance imaging (MRI). Performing numerical simulations and
experiments with a 1.5 T MR scanner, we reconstruct the associated topological
edge mode profiles and demonstrate their feasibility for sensitivity
enhancement of conventional radiofrequency coils.
