Dipole antenna designs were introduced to pre-clinical spinal cord imaging at ultra-high field. The tuning and matching circuit can be adapted to both 9.4 T and 14.1 T magnet with simple adjustment. Dipole antennas provided good longitudinal coverage for the animal, and optimal penetration for spinal cord imaging. In terms of transmit efficiency and field homogeneity over rat spinal cord, dipole antenna design is a flexible and promising candidate for ultra-high field imaging.
