  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.
