Construction of a loop-gap-resonator RF coil for MR microscopy of ex vivo mouse brains at 15T is described. The large signal obtained allowed acquisition of 20μm³ isotropic voxels, the highest resolution yet achieved in MR mouse brain imaging. Importantly, the high resolution allowed clear identification of multiple brain structures and will be of interest to researchers working with various mouse models.
