Magnetic Resonance (MR) imaging and spectroscopy play crucial roles in modern clinical diagnoses and research. At the same time, MR system performance is limited by several critical factors, one is low signal-to-noise ratio (SNR), which is critical to produce high quality diagnostic images. To address this issue and improve system performance, researchers from the University of Minnesota have developed an ultrahigh dielectric constant ceramic material to be used in conjunction with RF coils in MR systems. This ultrahigh dielectric material allows for varying permittivity at different operating frequencies. The advantages of this technology include denoising effect, high RF coil transmission & reception efficiencies, and improved SNR for magnetic resonance or spectroscopic imaging applications. This novel technology is robust and cost-effective and could largely improve imaging sensitivity and resolution, which is critical for biomedical research and clinical diagnostics.
