Magnetic Resonance Imaging (MRI) is a medical imaging technique used in the diagnosis and follow-up of diseases. However, magnetic susceptibility mismatch between human tissue and foreign metallic objects such as stents or implants can induce the distortions in MR images. In order to solve the problem, new algorithms to adjust the artifacts have been developed. While, it is very difficult to develop novel biomaterials having not only biocompatibility and excellent mechanical properties but also low MR image distortion. We propose a way to reduce the MR image distortion while maintaining the inherent biocompatibility and mechanical properties. The magnetic susceptibility mismatch between human tissue and biomaterials such as NiTi alloys that have paramagnetic property can be offset by coating carbon-based materials with strong diamagnetic property. After coating the carbon-based materials on the surface of the NiTi alloys, their magnetic susceptibilities were analyzed and MR image distortion was evaluated.
