Sodium MRI is useful in knee imaging to identify articular cartilage pathology. Current coil design use four ring birdcages which limit the field-of-view and signal-to-noise ratio. We report significant improvement in the signal-to-noise ratio of sodium imaging with unchanged signal-to-noise of proton imaging using an optimized two birdcage coil design.
