Abstract

The travelling-wave MRI approach is an alternative to overcome the B1 inhomogeneity at UHF MRI for human applications. More recently, this concept has been also used with animal MR imagers. We used a parallel-plate waveguide and a bio-inspired surface coil to generate mouse images at 15.2T. Ex vivo mouse images were acquired without high dielectric materials to conduct the signal at the right frequency. These results are in very good concordance with results obtained at 3T and 9.4T. These results show that travelling wave MRI with high SNR can be performed with a simple waveguide.
